tests: improve concurrent blit tests

Browse Source 
By adding another testcase that follows up with a gpu read. This
checks whether the kernel properly tracks the pending write and
doesn't lose it (or sync up to the wrong seqno).

For some odd reason only the cpu mmap variant blows up, the gtt one
works here. I need to look into that some more.
