Stop auto-syncing retroarch-joypad-autoconfig-git from the AUR

The package carries a deliberate commit pin (59d557a) so every
architecture packages the same tree. The AUR sync kept trying to revert
that to the unpinned branch-tip recipe, recording a version downgrade in
the process. Mark it local so exactly one source owns the recipe; it is
Omarchy-maintained until it moves to an upstream release feed.
