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

Browse Source 
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.

(From OE-Core rev: fac12de72bda1e864e71538be07d6c6f6e987498)
