[igt-dev] [v4 i-g-t] tests/kms_busy: Limit the execution to two pipes

As all pipes are symmetric, restrict the execution to two pipes
can save lot of CI time.
If we want to execute on all pipes, we need to pass an extra
argument "-e" indicates extended.
Example: ./build/tests/kms_busy -e --r basic
V2, V3:
* Fix the typo in args handler (Petri)
V4:
* Handle clampling cleanly (Petri)
* Restore lost test coverage in the previous version (Petri/Bhanu)
