[Feature request] Remove the mkinitcpio presets when uninstalling a kernel

[BillFleming]

Describe the bug
At least in Arch when installing the pkg* files then uninstalling them later it leaves behind preset files in the mkinicpio directory that you then have to remove manually. If you don't remove them it will try to run mkinicpio on the uninstalled kernels, which piles over time. Not sure yet if this happens on Debian but will check.
