Adds a systemd one-shot service to amend the bootloader on a successfully booted, new kernel entry using the -no-boot-next option. Should a newly installed kernel panic while booting, no changes will occur in the boot loader and the service ensures BootNext is not set again on the bad kernel (unless another evocation of nullbootctl does). In the event that a new kernel successfully boots, nullboot will amend the boot loader with the new kernel.

This is the first systemd service I've written, so feel free to nit pick anything. I did test that this works with my changes to ubuntu-boot-test.
Also note: we cannot merge this until the changes from #144 reach the
ubuntu/mainbranch since it requires theno-boot-nextflag and the new fallback-mechanism to be enabled.
