avcodec/fft: fix INTERL macro on 3dnow

The commit b7c16a3f2c4921f613319938b8ee0e3d6fa83e8d ("x86: fft: Port to
cpuflags") breaks the opus decoder in ffmpeg when compiling for 3dnow. The
output is audible, but there's a lot of noise.

The reason for the breakage is that the commit unintentionally changed the
INTERL macro so that it is empty when compiling for 3dnow. This patch
fixes it.
