Improve subtest selection logic when using -t/-a/-d parameters.
In particular, more than one subtest can be specified or a
combination of tests / subtests.
-a send_signal -d send_signal/send_signal_nmi* - runs send_signal
test without nmi tests
-a send_signal/send_signal_nmi*,find_vma - runs two send_signal
subtests and find_vma test
-a 'send_signal*' -a find_vma -d send_signal/send_signal_nmi* -
runs 2 send_signal test and find_vma test. Disables two send_signal
nmi subtests
-t send_signal -t find_vma - runs two *send_signal* tests and one
*find_vma* test
This will allow us to have granular control over which subtests
to disable in the CI system instead of disabling whole tests.
Also, add new selftest to avoid possible regression when
changing prog_test test name selection logic.

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.
Before:
$ ./test_progs -n 2,4-
#2 atomic_bounds:OK
Summary: 1/0 PASSED, 0 SKIPPED, 0 FAILED
After:
$ ./test_progs -n 2,4-
Failed to parse test numbers.

bpf_program__set_extra_flags has just been introduced so we can still
change it without breaking users.
This new interface is a bit more flexible (for example if someone wants
to clear a flag).

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.

Move testing prog and object load wrappers (bpf_prog_test_load and
bpf_test_load_program) into testing_helpers.{c,h} and get rid of
otherwise useless test_stub.c. Make testing_helpers.c available to
non-test_progs binaries as well.

Add testing_helpers.c, which will contain generic helpers for test runners and
tests needing some common generic functionality, like parsing a set of
numbers.
