The function does not check that parsing_end is false after parsing
argument. Thus, if the final part of the argument is something like '4-',
which is invalid, parse_num_list() will discard it instead of returning
-EINVAL.

After recent refactoring bpf_prog_test_load(), used across multiple
selftests, lost ability to specify extra log_level 1 or 2 (for -vv and
-vvv, respectively). Fix that problem by using bpf_object__load_xattr()
API that supports extra log_level flags. Also restore
BPF_F_TEST_RND_HI32 prog_flags by utilizing new bpf_program__set_extra_flags()
API.
