    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.
