Anyway we can simply extend the option parsing locally? (Just find it
unsightly to have test specific options in libigt.)

Stashing argc/argv in igt_subtest_init_parse_opts() and then being able
to run getopts inside igt_main {}?

I also had in mind an env for module options, which may be also useful
for the module reloading and autoloading.
