Add/Remove Some @KnownFailure Annotations

Bug 2639444 2564250 2639393

Remove the @KnownFailure annotations form tests now passing in
Froyo for Nexus One using the CTS test runner. Put on
@KnownFailure annotations for those that are failing but passing
with the run-core-tests test runner.

MultiSocketTest is an exception that doesn't seem to make sense,
and fails in both runners.
