Attempting to install `git` on the `pacboy` line fails with `error: target not found: mingw-w64-clang-x86_64-git` so move that to another spot. `video_mp_image_pool.c` fails to build due to libavutil right now because of missing vulkan headers so install those with `pacboy`. (also improved in https://github.com/mpv-player/mpv/pull/14610 ) Simplify package lists since pacboy doesn't require `:p` anymore.
