tests/kms_chamelium: test we receive a signal from both audio channels

This commit updates the audio test to make sure we receive a signal from both
audio channels. However this commit doesn't check that left and right channels
are not swapped. Such a check requires some more work (because the Chamelium
device does swap left and right channels) and will be implemented in a future
commit.

This commit adds a new channel argument to audio_signal_add_frequency, to add
a frequency to a single channel only.

Some light refactoring has been performed: a proper audio_signal_fini
function has been introduced and size_t in now used when it should be.
