tdf#95843: Wait for fire_glxtest_process also in --headless mode

Discussed with mmeeks on IRC that fire_glxtest_process is probably called as
early as possible so that its reuslt is ready by the time it is needed in the
non-headless case.  So best fix for headless is probably to just wait for the
sub-process at an opportune point, instead of redesigning the whole mess so that
fire_glxtest_process would only be called once its result is actually needed.
