audioserver: Remove direct dependency on IAudioRecord.aidl

audioserver should not link directly the code generated from
IAudioRecord.aidl because it also gets it as a result of
depending on libmedia.so and other libraries.

Linking IAudioRecord.o directly causes violation of ODR
because it contains global data.
