Use PFFFT for WebAudio FFT on Android

Replace the OpenMAX DL FFT with PFFFT for WebAudio on Android.

Roughly, the library is as fast or faster than OpenMAX DL FFT and is not
a giant blob of handwritten assembly code. See the bug for a link for
additional information.

The changes in the tests are due to minor changes in accuracy. Apparently,
PFFFT is very slightly less accurate than OpenMAX DL. We deem these small changes
to be acceptable for the performance gain and readability.
