selftests/bpf: add sockopt test 



Add sockopt selftests:
* require proper expected_attach_type
* enforce context field read/write access
* test bpf_sockopt_handled handler
* test EPERM
* test limiting optlen from getsockopt
* test out-of-bounds access

v9:
* add tests for setsockopt argument mangling

v7:
* remove return 2; test retval=0 and optlen=-1

v3:
* use DW for optval{,_end} loads

v2:
* use return code 2 for kernel bypass
