meson.bbclass: Fix build issues with /tmp mounted with noexec

Since commit d297f7ebf3f6 [fribidi: use Meson instead of autotools]
build failures have been observed with this package. The immediate
issue was related to improperly named #defines per
https://github.com/fribidi/fribidi/commit/46f52d588ab5, however, the
root cause was FRIBIDI_SIZEOF_INT getting a value of "-1".

After searching the meson logs the following was found:

  Could not run: /tmp/tmp2fxe6ha1/output.exe (error: [Errno 13] Permission denied)
  Checking for size of "int": -1

Which pointed to the real root cause being /tmp mounted with noexec, a
common configuration on Redhat and other distros. This issues has been
raised in the meson community:
https://github.com/mesonbuild/meson/issues/2972 but is yet to be
addressed.

Using the discussion from issue#2972 and the fact that the underlying
code makes use of python 'tempfile' we can simply create a 'tmp'
directory and make use of TMPDIR to avoid this issue.
