CRAS: cras_shm: rename shm_area to shm_header
In preparation for a split shm:
rename cras_audio_shm_area to cras_audio_shm_header
rename cras_audio_shm's field 'area' to 'header'
update all references to the renamed struct/struct field.
Also slightly clean up shm setup logic for dev_io_stubs and
audio_thread_unittest.
Since this is just a rename of some fields, no functional changes
are expected.
