runqemu: add ability to skip using an existing tap device
Support the sitauation where a user could have another VM running
which uses tap devices. To prevent runqemu from trying to use the
same tap device, runqemu will skip using a tap device if it finds
a filename tapX.skip within its lock directory.
This fixes [YOCTO #5815]
