selftests/bpf: Test for map update access from within EXT programs

Browse source

This adds further tests to ensure access permissions and restrictions
are applied properly for some map types such as sock-map.
It also adds another negative tests to assert static functions cannot be
replaced. In the 'unreliable' mode it still fails with error 'tracing progs
cannot use bpf_spin_lock yet' with the change in the verifier
