[pve-devel] [PATCH manager] 8 to 9 checks: do not ask bootctl if systemd-boot is used.

[Stoiko Ivanov]

The current logic of deciding if systemd-boot was manually setup by
the user (without proxmox-boot-tool), by checking
`bootctl is-installed` yields a false-positive after upgrading:
* systems which have the package installed (e.g. from our isos after
  8.0), but do not use proxmox-boot-tool (LVM installs) will get
  systemd-boot installed to /boot/efi upon upgrade
* after upgrading the check says that it's been explicitly setup.

Rather warn if the package is installed (unless proxmox-boot-tool is
used and the upgrade is still not done) in any case - as the number
of systems which have it setup manually are probably far lower than
those that upgrade without explicitly checking pve8to9.
