Remove failure expectations in WPTServeExpectations for tests which use navigator.getUserMedia.

In addition to removing the failure expectations associated with http://crbug.com/608457, this CL also sorts expectation lines in the file, and changes expectations based on local runs on my workstation:

Added pass expectations:
 crbug.com/508725 imported/wpt/html/semantics/embedded-content/the-iframe-element/iframe_sandbox_allow_script.html [ Pass ]
 crbug.com/508725 imported/wpt/mediacapture-streams/GUM-trivial-constraint.https.html [ Pass ]
crbug.com/508725 imported/wpt/pointerevents/pointerevent_constructor.html [ Pass ]

Removed failure expectations:
 crbug.com/508734 imported/wpt/html/rendering/replaced-elements/svg-embedded-sizing/svg-in-iframe-fixed.html [ Timeout ]
