[PATCH 0/2] rtla: Add tests for option parsing with attached arguments

[John Kacur <jkacur@redhat.com>]

This patch series adds comprehensive tests to verify that short options
with attached numeric arguments (e.g., -p100) work correctly across all
rtla commands.

These tests complement Tomas Glozar's fix "rtla: Fix parsing of
multi-character short options" which resolves the issue where options
like -p100 were incorrectly parsed as multiple separate options due to
getopt_long() being called twice.

The tests verify four option formats for each command:
  -p 100        (short with space)
  -p100         (short attached - previously broken)
  --period=100  (long with equals)
  --period 100  (long with space)

Commands tested:
- timerlat hist and top
- osnoise hist and top
- hwnoise

All 20 tests pass with Tomas's fix applied, confirming the issue is
resolved and preventing future regressions. These tests will continue to
work when rtla transitions to libsubcmd in the future, ensuring this
functionality remains correct across parsing implementations.

Note: Patch 1/2 is a resend of the timerlat hist tests sent previously.
Patch 2/2 adds tests for the remaining rtla commands.
