Mark the speaker detection check as fixme

Chromium's fake microphone never registers as a speaker at the SFU, and Firefox's steady tone does so in about two runs out of three, with or without the browser's audio processing. The test stays, out of the gate, until the dev SFU gets a lower speaker threshold or the harness a louder fake device.
