Conditional code for OpenSL ES float format on API 21+ won't work

[dturner]

This code (which I wrote) is intended to determine whether floating point format is available on this device based on the runtime API level:

https://github.com/google/oboe/blob/master/src/opensles/AudioOutputStreamOpenSLES.cpp#L112

However, __ANDROID_API__ is a preprocessor define so will give the compile time API level (usually API 16) so floating point won't be available on any device.
