Zbigniew Jędrzejewski-Szmek 12391431c2 machined: add description to varlink server, unify error messages
manager_varlink_init_resolve_hook and manager_varlink_init_userdb are very
similar, but one didn't set a description and the other one had an error
message which didn't print the offending path.

Define constants for the paths, and also change other similar constants
to have slightly shorter names. (It's an "address" and "path", but we don't
need to have both parts in the name, esp. that it makes the name very long.)
