rtla/tests: Extend timerlat top --aa-only coverage
rtla-timerlat-top's --aa-only option is currently only tested for return
value.
Extend the tests to also check that only auto-analysis is being done via
a negative match for the "Timer Latency" text in the top header, and
further split the test case into two:
- one test case for --aa-only stopping on threshold
- one test case for --aa-only exiting without threshold being hit
For both cases, the expected output ("analyzing it" or "Max latency was"
respectively) is checked against in addition to the negative match.
