mkosi: Drop building custom kernel logic

Now that mkosi-kernel is a thing, this logic in systemd is just mostly
bitrotting since I just use mkosi-kernel these days. If I ever need to
hack on systemd and the kernel in tandem, I'll just add support for
building systemd to mkosi-kernel instead, so let's drop the support for
building a custom kernel in systemd's mkosi configuration.

-## Hacking on the kernel + systemd
-
-If you're hacking on the kernel in tandem with systemd, you can clone a kernel repository in mkosi.kernel/ in
-the systemd repository, and mkosi will automatically build that kernel and install it into the final image.
-To prevent the distribution's kernel from being installed (which isn't necessary since we're building our
-own kernel), you can add the following snippets to `mkosi.local.conf`:
-
-(This snippet is for Fedora, the list of packages will need to be changed for other distributions)
