Fix FFMPEGMediaPlayer: static init block issue, libavresample debian8 packaging

- static init block issue
  commit 06a05d30fc026b21f59310986ea9eb7f3ff30d54
  used a static final field initialized after the static {} block
  which was still null if called -> moved above static {}

- libavresample debian8 packaging
  Debian8 packages a libav10 combination w/ libavresample version 2,
  which actually belongs to libav11 - libav10 uses libarvresample version 1.
  Allow libavresample and libswresample to be selectively skipped if version mismatch.
