avcodec: Remove the FFT_FIXED_32 define
...
Since the removal of the 16-bit FFT said define is unnecessary as
FFT_FIXED_32 is always !FFT_FLOAT. But one wouldn't believe it when
looking at the code.

Rename CONFIG_FFT_FLOAT ---> FFT_FLOAT
...
The define does not originate from configure, so it should not
have a name that is CONFIG_-prefixed.
