Since the output needs to be the same, regardless if the module is
compressed, change populate-modules.sh to conditionally compress the
module if that feature is enabled.

This way we can execute the tests with any build-time configuration and
it should still pass.

Hello,

thanks for the patch.

I tested it and it allows me to run tests with zstd disabled.

It also makes the code much clearer.

Great, thank you!

nit: using grep single time is IMHO enough
grep -q "define KMOD_FEATURES.*\+$feature" $CONFIG_H

Thanks!

BTW I still have issues with testsuite/test-depmod locally, but probably my
wrong setup (testing also other configure options than this one):
