scripts/runqemu: Don't print error messages about tap file locks

Errors like:
runqemu - ERROR - Acquiring lockfile /tmp/qemu-tap-locks/tap0.lock failed: [Errno 11] Resource temporarily unavailable

are not really fatal errors. Change these to info messages instead
so people look later in the log for the real errors.
