Subject: packages: linux-kernel: T2698: add missing patch for wireguard build

When importing the old Kernel Pipeline the use .gitignore file prevented a patch
from beeing imported as it matched the entire wireguard directory. With this
in place we did not build the wireguard.ko kernel module but failed back to DKMS
which we do not support.
