selftests/bpf: Add test for freplace program with write access
This adds a selftest that tests the behavior when a freplace target program
attempts to make a write access on a packet. The expectation is that the read or write
access is granted based on the program type of the linked program and
not itself (which is of type, for e.g., BPF_PROG_TYPE_EXT).
This test fails without the associated patch on the verifier.
