freeswitch-stable: Misc fixes

- compile fix for mod_av added, without it the build errors out
  (warnings turned to errors). It's still labelled @BROKEN, but once
  OpenWrt's ffmpeg maintainers add libavresample to libffmpeg-full
  (PR #4490) it should work.
- disable Erlang detection if mod_erlang_event is not selected (build
  dep on Erlang unfortunately has to stay)
