Add a few more (128) loops to the page full of MI_STORE_DWORD in an
attempt to try and slow down the execution to the point where a
full-debug kernel can beat the GPU.

With lockdep enabled, the driver overhead is enormous and we need to
slow down the GPU to compenstate (otherwise the GPU is already idle when
we expect busyness). So do more work per batch.

A little more inelegant as we can't control the delay very well, but it
should prove more vesatile and broaden the test coverge (and still be
quick enough for basic).

Now that gem_require_ring() does the right thing with BSD1/BSD2 we can
use it to our advantage here.

I dropped this from the list of rings for some tests when refactoring to
a common array. Almost all of the tests should be run over the default
exec engine to ensure ABI backwards compatiblity.

Exercise the busy-ioctl and verify it reports the right active engines
using the execbuffer notation.
