selftests: bpf: test_kmod.sh: Pass parameters to the module

Browse Source 
It's possible to specify particular tests for test_bpf.ko with
module parameters. Make it possible to pass the module parameters,
example:

test_kmod.sh test_range=1,3

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