tests: Disable failing tests until root cause determined

This should be a temporary change. Due to an issue, outlined here:
https://gem5.atlassian.net/browse/GEM5-1120, these tests have been
disabled. One of these tests, if not a combination of them, is causing a
timeout event to occur in the Nightly tests. They have therefore been
disabled until the exact cause of failure is established.
