Reduce the time waiting for the QEMU pidfile from three minutes to five seconds. The three minute time window was chosen to make sure QEMU had enough time to fully boot up. This, however, is an unreasonably long delay for QEMU to write the pidfile, which happens earlier when the QEMU process starts (not after VM boot). The three minute delay becomes noticeably wasteful in future tests that expect QEMU to fail and wait a full three minutes for a pidfile that will never exist.
