[pve-devel] [PATCH manager] pve8to9: rework systemd-boot checks

[Stoiko Ivanov <s.ivanov@proxmox.com>]

This patch replicates the changes done in pbs3to4 from:
https://lore.proxmox.com/pbs-devel/20250821141719.4130062-4-s.ivanov@proxmox.com/T/#u

The check if systemd-boot presence is not problematic (before
upgrade for systems that actually use it) is left in place with a
log_skip,, all other situations where systemd-boot is installed are
marked as failure and point to the upgrade guide in the pve-wiki.
