deploy.sh: print Include line using actual repo path, not hardcoded /opt/<slug>

The repo can be cloned to any directory (e.g. /opt/loreal-utilisation-dept
to match the Bitbucket repo name) — the slug we use for the URL path and
compose project is independent of the on-disk path. The previously printed
Apache Include line assumed `/opt/<slug>/`, which broke when the clone
location didn't match the slug. Use $APACHE_CONF (already absolute and
correct, derived from $SCRIPT_DIR) instead.
