[banshee] Add --disable-builtin-equalizer configure flag

[Bertrand Lorentz <blorentz src gnome org>]

commit 47edf3039e7288b642d131da6a09196b4c2d655f

    Add --disable-builtin-equalizer configure flag
    
    Builtin equalizer is always compiled by default. This flag allows the
    builtin equalizer to be disabled, forcing Banshee to use the system
    equalizer instead. This is favourable for distributions which have a
    suitably up to date gstreamer and thus have a fully working equalizer
    (bgo#583782).
