nongnu: make-linux-xanmod-source: Patch upstream kernel source instead.

* nongnu/packages/linux.scm (make-linux-xanmod-source): Patch upstream linux
source instead of downloading the auto-generated tarball from GitLab.
(make-linux-xanmod)[arguments]<#:phases>: Delete 'remove-localversion, moved
to snippet.
(linux-xanmod-source,linux-xanmod-lts-source): Adjust accordingly.
