automated: linux: ltp: kirk runner: parallelize tests

Add support for parallel test execution with the new LTP test runner,
kirk.  This update introduces the KIRK_WORKERS variable, which allows
you to configure the number of worker processes used for running tests
in parallel. This can significantly reduce test runtime on systems with
many CPU cores.
