[libvirt] [RFC PATCH 4/9] tests: qemucapsprobemock: Simplify and extract skipping of empty lines
The prettyfied output may sometimes contain empty lines which would
desynchonize the test monitor workers. The skipping code can be much
simplified though. Also a extract it so so that it's obvious what
it's doing and can be reused.
