RemoteAudioDestinationProxy::startRenderingThread is off by one when the
frame counter wraps

Reviewed by Chris Dumez.
The wraparound branch was unnecessary. Unsigned subtraction is defined modulo
2^32, so
totalFrameCount - m_lastFrameCount already yields the correct elapsed frame
count across a 32-bit
counter wrap. Drop the conditional entirely. (The original branch was also off
by one: it used
numeric_limits<uint32_t>::max() - m_lastFrameCount, which is one short of the
2^32 - m_lastFrameCount
needed.)
