Map broadcom-wl to broadcom-wl-dkms in the offline mirror list

Arch dropped the prebuilt broadcom-wl on 2026-09-02 and rebuilt broadcom-wl-dkms with replaces=(broadcom-wl). That only helps upgrades of an installed package; as an explicit pacman -Syw target the old name fails with "target not found", which broke the offline mirror download. Published runtime packages that predate the rename still list it in omarchy-other.packages, so rewrite it at build time until every channel ships a runtime naming broadcom-wl-dkms itself.
