test-definitions: kselftest upgrade to v5.10

[Naresh Kamboju]

If you are not using the test-definitions project to run kselftest,
please ignore this email.

A new run script for kselftest, run_kselftest.sh [1], was created during the
Linux v5.10 release.

This script allows someone to run both individual test cases and sets of
test cases. Accordingly, the test-definitions kselftest script [2] was also
improved to support these upstream changes [1].  Currently this change is in
the test-definitions repository in a separate branch "kselftest". This has been
running in LKFT's CI since November 2020 [3].

The test-definitions kselftest script will stop supporting older versions of
the kselftest run script starting 1st-Feb-2021 from master branch.
OTOH, One have to use test-definitions Tag 2021.01 (will be created) for older
kselftest versions.

We request that any users of test-definitions project start updating your
kselftest sources to version v5.10 and above.

Subject: 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".
