rtla/tests: Cover all hist options in runtime tests

Cover all options regarding histogram formatting for both
rtla-osnoise-hist and rtla-timerlat-hist tools. All options also have
output checking using positive or negative match, except for
-b/--bucket-size and -E/--entries, which cannot be tested in isolated
due to the output depending on the actual data collected.

Old -E/--entries test for rtla-osnoise was replaced with a new one
equivalent to the timerlat one.
