various tools: be more explicit when a glob is passed when not supported

See https://bugzilla.redhat.com/show_bug.cgi?id=1763488: when we say that
'foo@*.service' is not a valid unit name, this is not clear enough. Let's
include the name of the operation that does not support globbing in the
error message:

$ build/systemctl enable 'foo@*.service'
Glob pattern passed to enable, but globs are not supported for this.
Invalid unit name "foo@*.service" escaped as "foo@\x2a.service".
