Updating submodules

Prerequisites

Add a new remote to LAV Filters and FFmpeg submodules:

• for LAV Filters, git remote add upstream https://github.com/Nevcairiel/LAVFilters.git in src/thirdparty/LAVFilters/src
• for FFmpeg, git remote add upstream git://git.1f0.de/ffmpeg.git in src/thirdparty/LAVFilters/src/ffmpeg

Warning: Before updating LAV Filters always makes sure that no update is required on MPC-HC side. If there are some changes in LAV Filters interfaces or settings, some changes are likely to be needed in MPC-HC. If the update breaks compatibility with older LAV Filters versions, remember to update the version check in FGFilterLAV.cpp.
