runqemu: Ensure we process all tap devices

Browse Source 
The regexp in the script misses some tap devices, e.g. we see output like:

runqemu - INFO - Acquiring lockfile /tmp/qemu-tap-locks/tap25.lock failed: [Errno 11] Resource temporarily unavailable
runqemu - INFO - Acquiring lockfile /tmp/qemu-tap-locks/tap26.lock failed: [Errno 11] Resource temporarily unavailable
runqemu - INFO - Acquiring lockfile /tmp/qemu-tap-locks/tap27.lock failed: [Errno 11] Resource temporarily unavailable
runqemu - INFO - Acquiring lockfile /tmp/qemu-tap-locks/tap28.lock failed: [Errno 11] Resource temporarily unavailable
runqemu - INFO - Acquiring lockfile /tmp/qemu-tap-locks/tap40.lock failed: [Errno 11] Resource temporarily unavailable
runqemu - INFO - Acquiring lockfile /tmp/qemu-tap-locks/tap41.lock failed: [Errno 11] Resource temporarily unavailable

What happened to tap29 to tap39?

The issue is was we were missing devices with '0' in the number,
like "10:" and so on in the output from "ip link".
