devserver_util_test: Remove unimplemented tests

Two tests were added in 37761d10 which are not implemented, and cause
a failure. This prevents the ebuild from running other tests.

Disable these tests until they are implemented.

BUG=chromium-os:22954
TEST=FEATURES=test sudo -E  emerge cros-devutils
See that tests now complete
