ac97: switch to ShmStreamSource
Convert playback and capture for the AC97 device to use the zero-copy
ShmStreamSource instead of the old StreamSource.
In the process, rework start_playback and start_capture unit tests so
they rely less on sleep statements.

TEST="sox -n -r 48000 -b 16 output.raw synth 5 sine 330 &&
aplay -f dat output.raw" within a VM, check that sine wave is played
accurately.
