libs/faad2: Update to 2.8.1

* Switch back to upstream repo
* Follow the same configuration style as ffmpeg and mpg123 for using float vs
  fixed point codepaths.
* Remove unneeded cpp variables (musl provides C99 math library)

-		By default, libfaad2 will be built to use fixed point rather
-		than floating point math if emulated floating point operations
-		are being used. (See the CONFIG_SOFT_FLOAT option.) Set this
-		option if you would like to use floating point math regardless
-		of whether floating point emulation is in use.

-		For the best real-time decoding ability, leave this option off.
