build-kernel: release .rpm alongside .deb + .pkg.tar.zst (#22)

Now that ps5-linux-image's --distro all also produces an .rpm (paired
image PR), pick it up in the artifact upload, checksum list and
release files: block. Also add rpm as an explicit format choice so
someone can dispatch an rpm-only kernel build.

The sha256sum pipeline gets a 2>/dev/null so it doesn't complain
when an older ps5-linux-image checkout is used that only writes
deb + pkg.tar.zst.

-If you use Arch Linux, then additionally do:

-If you are updating Linux on your external USB SSD or if you are directly booting into M.2 SSD, i.e. if you use `-m2` in `cmdline.txt`, then you have to update the files on the FAT32 partition of your USB drive:
-
-```bash

-sudo cp /boot/initrd.img /boot/efi/initrd.img
