Subject: [PATCH] fix(boot): cap the systemd-boot entries at ten per host

Without configurationLimit every generation keeps its entry on the ESP.
The desktop had grown to 58 of them, 232M of a 1G partition, and nothing
ever removed one. Ten keeps a useful rollback range and lets the builder
clear the rest on every switch.
