audio/ardour6: Update to 6.9.0

Fix MP3 audio export. It was unavailable due to missing ffmpeg_harvid and
ffprobe_harvid in $PATH.

Add dependencies on harfbuzz and fftw3 libraries, which were implicitly linked.

While here, pet linters.

audio/ardour6: fix build on GCC architectures

Undefine _POSIX_SOURCE to make macros in errno.h available:
/usr/local/lib/gcc9/include/c++/powerpc64-portbld-freebsd12.1/bits/error_constants.h:42:40:
error: 'EAFNOSUPPORT' was not declared in this scope
   42 |       address_family_not_supported =   EAFNOSUPPORT,
      |                                        ^~~~~~~~~~~~
/usr/local/lib/gcc9/include/c++/powerpc64-portbld-freebsd12.1/bits/error_constants.h:43:28:

      |                            ^~~~~~~~~~

Also tested to build with Clang.
