Mk/*: Build with a clean environment

Both our make and gmake use the MAKEFLAGS environment variable but the
values aren't compatible and the latest version of gmake complains about
that.  To rule out that any environment variable can cause problems like
this, add a new command SETENVI=/usr/bin/env -i that clears the
environment, and use it to run upstream build systems with a clean
environment.

Introduce a new variable WRK_ENV that contains the environment to use
with SETENVI in all targets that run upstream build commands.  Variables
that are common between CONFIGURE_ENV and MAKE_ENV could be moved to
WRK_ENV but for now it just contains a minimal environment:

HOME=${WRKDIR}: Fixes USES=elixir ports that were using the user's HOME.
OSVERSION: For cross building; determines the output of uname -K and
getosreldate(3); affects net/freebsd-telnetd for example.
PATH: Fixes USES=gem ports that were using the user's PATH.
PWD=$${PWD}: Preserve current working directory; affects USES=go ports.
TERM: To preserve colored output to terminals.
TMPDIR: For users who define that.
UNAME_*: For cross building; determines the output of uname(1); affects
lang/python* for example.

This commit deals with everything under Mk/.  Ports that have their own
targets running upstream build commands can switch to SETENVI later.

The ports tree adds its definition of ARCH to the MAKEFLAGS environment
variable, which is interpreted by sub-makes as command line arguments,
which means that any definition of ARCH in upstream makefiles was
overridden.  The following ports required fixes now that this is no
longer the case.

games/iortcw, games/q3cellshading, games/tremulous:
These use Quake 3 engine code.  Fix use of ARCH.  Reduce diff between
FreeBSD code and Linux code.

games/legesmotus:
Remove ARCH related patches.

lang/ocaml:
Patch configure script so it detects amd64 correctly.  Also make the
powerpc case consistent with the other architectures.  This also affects
other ocaml ports like devel/ocaml-ocamlbuild and math/ocaml-num that
include a Makefile.config installed by lang/ocaml.  While here, use
SETENVI in check-test target.

net/libnatpmp:
Use of upstream definition of ARCH triggers installation in PREFIX/lib64
on amd64.  Disable this.

Mk/Uses: Add pytest.mk

Add USES=pytest, a standardized pytest entry point.

This knob adds dependency on pytest and defines do-test target which
calls it "the right way" (respecting TEST_ENV, with proper verbosity,
additional info on skipped tests, and resetting addopts which may
be set by upstream and introduce unwanted options). This allows to
remove duplicate (and in many cases not completely correct) do-test
targets from a lot of pytest consumer ports.

Additionally, it adds PYTEST_IGNORED_TESTS (to list tests which
fail and are expected to fail) and PYTEST_BROKEN_TESTS (to list
tests which fail and needs to be fixed). Both knobs lead to
listed tests being skipped, which is believed to be better than
