selftests/bpf: add test selectors by number and name to test_progs
Add ability to specify either test number or test name substring to narrow down a set of test to run. Usage: sudo ./test_progs -n 1 sudo ./test_progs -t attach_probe Signed-off-by: Andrii Nakryiko <andriin@fb.com> Signed-off-by: Alexei Starovoitov <ast@kernel.org>
