Pitch compensation on speed effect doesn't seem to work

[Eugen Mohr]

Hello

The rubberband lib integration into MLT is not proper done so far. You
have to manually do the following:

lib/pkgconfig/fftw.pc rename to fftw3.pc

compile rubberband

compile vamp-plugin-sdk

compile ladspa-sdk

On the end compile and merge MLT again. This should enable rubberband in
MLT which will handle the pitch compensation.

Or you wait until the rubberband integration is done correctly.
