sys-kernel/asahi-sources: add 6.8.6_p1

The asahi GPU driver builds with rust 1.76 and 1.77.

Other changes:
- handle asahi tags for stable releases
- Save the sources as "linux-${TAG}.tar.gz" (i.e.
  linux-asahi-6.8.6-1.tar.gz) to share the tarball with the asahi-kernel
  ebuild in a ebuild overlay
