audioconvert: align low-/highpass calculations
...
The current biquad calculations are based on RBJ's cookbook [1],
except for low-/highpass. Since the filter configuration is also
based on using the definition of Q, it makes sense to also align
the remaining calculations to use the same filter cookbook instead
of using resonance which doesn't result in the same coefficients
as when using Q.

config.h is a local header, not a system one
...
Change the #include accordingly, that's what we use in the rest of the tree
too.
