proxmox-boot: divert call to grub-install to p-b-t init

This way all ESPs (in case of a legacy booted system) get an
updated grub installation.

running only once between reboots (the markerfile is in /tmp) should
be enough. Sadly the environment does not provide a hint which version
grub is installed to.
