kernel-install: add default install scripts

Do the depmod in the kernel-install hooks, so hooks can produce/install
kernel modules and be part of the depmod.

Also move the basic boot loader entry creation and removal to a
plugin script.

If PRETTY_NAME is not defined in /etc/os-release, fallback to
PRETTY_NAME="Linux $KERNEL_VERSION".

Add documentation for everything in the man page.
