[PATCH bpf-next] selftests: bpf: test_kmod.sh: pass parameter to the module

[Yauheni Kaliuta <ykaliuta@redhat.com>]

It's possible to specify particular tests for test_bpf.ko with
module parameters. Make it possible to pass a module parameter as
the first test_kmod.sh argument, example:

test_kmod.sh test_range=1,3

Since magnitude tests take long time it can be reasonable to skip
them.
