igt/gem_concurrent_blit: Disable userptr+child tests
The issue here is that the pointer inherited upon the child is
copied-on-write, i.e. the pointer is private to each process, but the
handle is shared. This means that writes and reads in the child are
going to a different set of pages than the GPU's object - the test is
simply broken. To overcome this we would need to mmap the shared buffer
into the child.
