systemctl: refuse to acquire dbus connection with --global
Maybe, better to check the runtime scope each verb for better log
message, but this is a good start point to not trigger assertion.
Fixes oss-fuzz#56915 (https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=56915).
Fixes #26402 and #26754.
