[PATCH i-g-t] lib/igt_kmod: Allow to load kunit from alias

[Lucas De Marchi]

Instead of only allowing to load the from the module name, also allow it
from alias by using kmod_module_new_from_lookup(). With that a user can
have their on aliases and the kernel can also export a compat alias for
future module renames.
