obs-ffmpeg: Fix build with FFMPEG 8 and above

With commit https://github.com/FFmpeg/FFmpeg/commit/822432769868 FFMPEG
has removed almost all of the FF_API_FF_PROFILE_LEVEL related defines.
They were deprecated since 2023-09-06. This results in build failures.

This is first found on Gentoo with FFMPEG pre-release version.
