These tests require DRM master right, so make sure they have it from the
beginning. This gives an early indication if another DRM master is running
and makes the given test skip (with a proper explanation of the reason)
instead of exiting with error.

Since relocations are variable size, depending upon generation, it is
easier to handle the resizing of the batch request inside the
BEGIN_BATCH macro. This still leaves us with having to resize commands
in a few places - which still need adaption for gen8+.

Also run the script while at it.

The kernel full ppgtt support has a bug where it can drop a pinned
fence to the floor, hence we leak the pin_count as the subsequent
fence unpin becomes a nop. We can trigger it easily by unbinding a
buffer from a ppgtt address space while the buffer is simultaneosly
being used for scanout.
Make the kernel leak the fence pin_count and trick it into picking
a new fence register for the next scanout buffer. Looping like
this for a while we leak the pin_count for all fence registers after
which the kernel can no longer find a new fence register when it needs
one. As a result we get back a SIGBUS from the GTT mmap access.
