Fix race in WebRtcGetUserMediaBrowserTest

Fix race in WebRtcGetUserMediaBrowserTest

Some test cases raced because each case was changing a global feature flag potentially in parallel.
Instead of having separate test cases that each set the flag, have separate tests objects for each
value of the flag, and set the flag in the constructor to avoid races.
