Kumar Kartikeya Dwivedi 8218ccb5bd selftests/bpf: Add tests for kfunc register offset checks 
Include a few verifier selftests that test against the problems being
fixed by previous commits, i.e. release kfunc always require
PTR_TO_BTF_ID fixed and var_off to be 0, and negative offset is not
permitted and returns a helpful error message.
