systemd assumes that the ESP partition is mounted on /boot. Instead debian
seems to suggest to mount it on /boot/efi/.
(systemd) bootctl relies on this assumption. The user could override this
default via the --path switch, but this is annoing.
The patch below adds a check: if the /boot/efi/EFI directory exists, bootctl
assumes that the ESP is mounted on /boot/efi, otherwise /boot.
Anyway the user can still override the default using the --path switch.
I proposed the patch upstream [1] but it was rejected becuase the systemd
developers want to support only mounting ESP on /boot.

These days bootctl examines /efi, /boot and /boot/efi to determine where
the ESP is mounted, so I think this bug is obsolete.
