qtdemux: set alac caps using info from codec buffer

qtdemux cannot decode ALAC files with 96kHz/24bit audio. For some reason the
samplerate field in the STSD atom is not right, so the audio caps must be
extracted from the codec data. This is what the libav mp4 demuxer does.

Here is an example file:

gst-launch-1.0 playbin
uri="http://absolut.zogzog.org/share/samples/m4a/alac-96k.m4a"
