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] Signed-off-by: Scott Garman <scott.a.garman@intel.com> Signed-off-by: Richard Purdie <richard.purdie@linuxfoundation.org>
