[PATCH 1/4] coreaudio: rename misnamed variable fake_as

["Volker Rümelin" <vr_qemu@t-online.de>]

While the variable once was used to fake audio settings, since
commit ed2a4a7941 "audio: proper support for float samples in
mixeng" this is no longer true. Rename the variable to obt_as.
This is the same naming scheme as in audio/sdlaudio.c
