selftests/bpf: add regression test for bpf_d_path()
Add a regression test for bpf_d_path() to cover incorrect verifier
assumptions caused by an incorrect function prototype. The test
attaches to the fallocate hook, calls bpf_d_path() and verifies that
a simple prefix comparison on the returned pathname behaves correctly
after the fix in patch 1. It ensures the verifier does not assume
the buffer remains unwritten.
