Pin omarchy-mac to omarchy-mac-pkgs 60d03b7 for mpv on a Mac without a GPU driver (#1551)

maralcbr participates in package commits attributed to Marcelo Alcantara on omarchy-pkgs' master branch. omacom/omarchy-pkgs@ccde0079f8b7 enables runtime EFI variable writes, while omacom/omarchy-pkgs@4323333a6dfb saves those variables at shutdown so boot-menu requests and boot configuration changes reach the next boot.

omacom/omarchy-pkgs@0aac17f135ec makes T8122 external-display firmware reservation opt-in after an M3 Air internal-display failure, leaving external displays disabled by default there. Separately, omacom/omarchy-pkgs@fccc4321b01e updates the Mac package configuration so mpv can use software rendering when no GPU driver is available. These are committed package changes, rather than evidence of a stable Omarchy release.
