Resolve recursive kanidm-unixd require
    
    With the introduction of the "require_in" on
    "remove_old_ldap_auth_packages" in
    11c2df43fd47f07ea573321bd92b42942d14588d, Salt failed
    kanidm-unixd.service with "Recursive requisite found".
    While it is not clear why the situation is treated as recursive,
    the require on kanidm-unixd is dropped as its implicit dependency
    should be sufficient.
