audacity: 2.4.1 -> 2.4.2

A few other things:
 - prep for transition to gtk3 when audacity recommends it
 - we drop the runtime linking with lame as audacity is picking it up on
   its own
 - on linux, add a number of missing dependencies.
 - use a newer (recommended) wxwidgets
 - add a patch (merged upstream) that makes audacity follow XDG for file locations
