tests, mem-ruby: add GPU Ruby random tester to nightly tests

The input has been sized to take around 30 seconds and provide good
coverage for the coherence protocol.

+# first run the GPU protocol random tester -- it should take about 30
seconds
+# to run and provides good coverage for the coherence protocol
+# Input choices (some are default and thus implicit):
+# - use small cache size to encourage races
+# - use small system size to encourage races since more requests per CU
(and faster sim)
+# - use small address range to encourage more races
+# - use small episode length to encourage more races
+# - 50K tests runs in ~30 seconds with reasonably good coverage
+# - num-dmas = 0 because VIPER doesn't support partial cache line writes,
which DMAs need
