test/gem_lmem_swapping: fix physical engine usage

During execbuf DG2 currently just hits:

	"execbuf with unknown ring: 5"

It looks like the fix is to convert the test over to using the
non-legacy API where we instead fill the ctx with all the physical
engines and then engine/ring becomes the index into this.

v2:
  - Make sure we destroy our newly created contexts(Ashutosh)
  - Tweak the commit message so that we are talking less nonsense(Tvrtko)
  - s/i915/fd/ when calling set_persistence
