Restrict default filesystem access to ~/.MakeMKV and ~/Videos

[joshua-stone]

Qt can use the file picker portal to gain write access to specific directories from within the sandbox.

This seems to work for scenarios like:

• setting alternative data directories
• writing files to external drives

Filesystem access can be tested by setting a data directory through the file picker:

$ flatpak run --nofilesystem=home --filesystem='~/.MakeMKV:create' com.makemkv.MakeMKV

Then run find on the directory:

$ flatpak run --nofilesystem=home --filesystem='~/.MakeMKV:create' --command=sh com.makemkv.MakeMKV -c 'grep app_DataDir ~/.MakeMKV/settings.conf | cut -f2 -d \" | xargs find'

Wouldn't persist instead of filesystem be better for ~/.MakeMKV, or is there a reason it needs filesystem?
