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".

This is better than my previous patch and we can modify run_kselftest.sh
easily. The Documentation/dev-tools/kselftest.rst should also be update.

Thanks
