Subject: [PATCH v2 2/3] selftests/run_kselftest.sh: Make each test individually selectable

Currently with run_kselftest.sh there is no way to choose which test
we could run. All the tests listed in kselftest-list.txt are all run
every time. This patch enhanced the run_kselftest.sh to make the test
collections (or tests) individually selectable. e.g.:

$ ./run_kselftest.sh -c seccomp -t timers:posix_timers -t timers:nanosleep

Additionally adds a way to list all known tests with "-l", usage
with "-h", and perform a dry run without running tests with "-n".

While testing this patch set on LAVA the skip test functionality is not working.
We may have to revisit test definitions kselftest skip logic
or else
may add one more option to skip a given test on run_kselftest.sh script.

Yes, LAVA's hack to skip tests needs to be adjusted. Here's what it
should probably look like:
