linux-aurora: drop the generic linux provide and ship on edge only

The kernel provided linux=, so on any aarch64 root with the omarchy repo
listed before core, a dependency on linux resolved to this Apple-only kernel
instead of ALARM's linux-aarch64. linux-asahi and WIREGUARD-MODULE stay.

Channel membership narrows to edge until M1 and M2 cold-boot qualification;
promotion widens it again. pkgrel moves to 10 because 7.1.12.aurora2-9 is
already published and a filename is immutable.
