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

[John Kacur <jkacur@redhat.com>]

Add tests to verify that short options with attached numeric arguments
work correctly for all rtla commands after the parsing fixes.

Tests verify four formats for each command:
- Short option with space: -p 100
- Short option attached: -p100
- Long option with equals: --period=100
- Long option with space: --period 100

For osnoise and hwnoise commands, the tests also include -r 100 (runtime)
to satisfy the osnoise constraint that runtime <= period.

These tests complement the existing timerlat hist tests added in commit
d489b602c669 ("rtla/timerlat: Add tests for option parsing with attached
arguments").
