update-grub (via grub-mkconfig) generates the grub configuration by
concatenating the output of each snippet (from /etc/grub.d).
We need to redirect the output of `proxmox-boot-tool refresh`
to not end up with a syntactically wrong config in /boot/grub/grub.cfg
(which is not used in any case)

If the system seems to be using proxmox-boot, simply run it, in
addition to warning the user about the situation.
Since the warning is only printed when update-grub is not called
by dpkg or proxmoxmox-boot-tool, this should be safe, and potentially
help keeping systems bootable.

If the system seems to be booted using proxmox-boot, write a header at
the beginning of the grub.cfg generated when running `update-grub`
Additionally print a warning in case the script is run interactively.
This is determined by checking for DPKG_VERSION, which is set when
running as post-inst task (after a kernel install/removal)
and for PVE_EFIBOOT_UNSHARED, which is set by proxmox-boot-tool when
running `proxmox-boot-tool refresh.`
