Update expectations for WebSocket layout tests

interleaved-fragments.html, invalid-continuation.html, zero-length-text.html,
connect-src-websocket-allowed.html and handshake-error.html now pass.

All other WebSocket tests which were set to "Skip" have been changed to
"Failure", except for multiple-connections.html, which times out.

Tests of functionality which is not implemented in the new implementation
remain skipped. These are
FIXME-handshake-fail-by-null-subprotocol-selection-whitelist.html,
handshake-fail-by-no-cr.html and deflate-frame-*
