ao_coreaudio_utils: float is not a signed integer format 

kAudioFormatFlagIsSignedInteger implicates that it's only used with
integer formats. The mpv internal flag on the other hand signals the
presence of a sign, and this is set on float formats.

Until now, this probably worked fine, because at least AudioUnit is
ignoring the uncorrect flag.
