[ldapfeed] Reduce default value for user-attrs-map option (closes #3824889)
This is needed because lgc.configuration.Configuration does not allow
removing key/value pairs from the default (due to its use of
dict.update() internally).
Since CWUser.login is required, users of the add-source command will
always be able to override it.
