RBD: update expunge set for latest test, parameterize test script

Update expunge set for xfstests to known-good set for RHEL7 and Ubuntu 14.04.
Expunged tests without justifying comments are long-running and have not yet
been thoroughly investigated.

Add an environment variable (optionally passed from xfstests_url variable in
test YAML) to override the default xfstests repo.
