Reconcile aluminium with standard-noexim.

Aluminium was meant to include everything in standard-noexim except for
base::remote-syslog.  Rather than enumerate all of those packages
(which was done in role::fundraising::civicrm) I've added a specific
exception for aluminium to base::remote-syslog and changed
aluminium to a more normal node that includes standard-noexim.
