ftests/run.py: terminate processes that exceed timeout

Some commands, like 'cgrulesengd' in non-daemon mode, continue running
until explicitly terminated. Currently, we catch exceptions for timeouts
but do not terminate the lingering process. This patch ensures that such
processes are properly killed after the timeout.
