rtla/tests: Test timerlat -P option using actions

The -P option is used to set priority of osnoise and timerlat threads.

Extend the test for -P with --on-threshold calling a script that looks
for running timerlat threads and checks if their priority is set
correctly.

As --on-threshold is only supported by timerlat at the moment, this is
only implemented there so far.

rtla/tests: Add grep checks for base test cases

Checking for patterns in rtla output with grep was added to test rtla
actions. Add grep checks also for base tests where applicable.

Also fix trace event histogram trigger check to use the correct syntax
for the command-line option so that the test passes with the grep check.

rtla/tests: Limit duration to maximum of 10s

Many of the original rtla tests included durations of 1 minute and 30
seconds. Experience has shown this is unnecessary, since 10 seconds as
waiting time for samples to appear.

Change duration of all rtla tests to at most 10 seconds. This speeds up
testing significantly.

Before:
$ make check
All tests successful.
Files=3, Tests=54, 536 wallclock secs
( 0.03 usr 0.00 sys + 20.31 cusr 22.02 csys = 42.36 CPU)
Result: PASS

rtla/tests: Check rtla output with grep

Add argument to the check command in the test suite that takes a regular
expression that the output of rtla command is checked against. This
allows testing for specific information in rtla output in addition
to checking the return value.

Two minor improvements are included: running rtla with "eval" so that
arguments with spaces can be passed to it via shell quotations, and
the stdout of pushd and popd is suppressed to clean up the test output.
