Bug 1339327 (part 1) - Fix profiler_get_features(). r=mstange.

"unwinder" and "jank" are never checked for via hasFeature(), and are not
mentioned anywhere else in the profiler. This patch removes them from
profiler_get_features().

"restyle" *does* have a hasFeature() call and is handled by
profiler_feature_active(). This patch adds it to profiler_get_features().
