This is adding the timer timer tests as standard kselftests to be run by
the wrapper script...

...but this requires specific arguments to be run which the kselftest
runner won't supply.  I'd expect it to be a good default to enumerate
and test every possible device and generate a test for each.  However it
looks like this is really intended not as a standalone test but rather
as something run from within utimer-test, in that case it should be a
TEST_GEN_PROGS_EXTENDED.
