shells/bash: fix static build

files/patch-configure avoids having to run autoreconf in the port and can be
removed once the fix has been adopted upstream.
differential Revision: https://reviews.freebsd.org/D36849
Fix process substitution on systems without fdescfs (FreeBSD 5.x, 6.x)
While I'm here, use the official patchset instead of the custom ones
and reflect the port revision in the version number.
