alpine: remove deb/ubuntu-only resource & storage checks from update_script

check_container_storage uses 'df /boot --output=size' which is unsupported by
BusyBox df on Alpine and /boot is not a separate partition there. Both
helpers are designed for Debian/Ubuntu hosts only.

Affected: alpine-ntfy, alpine-rustypaste, alpine-ironclaw, alpine-redlib.

Fixes #14163
