Search $LIBFFI_TMPDIR also (#605)
Most temp file directories need to be hardened against execution, but
libffi needs execute privileges. Add a libffi-specific temp directory
that can be set up by sysadmins as needed with suitable permissions.
This both ensures that libffi will have a valid temp directory to use
as well as preventing attempts to access other directories.
