Clean up some update turds.
Cody updated his year old elabinelab and uncovered some problems with the update process. Note the updates to the install/updates scripts are just to add "MASTER_SITE_FREEBSD=1" to the make lines. This doesn't change anything functionally, it just speeds up the builds for older FreeBSDs where some of the MASTER_SITEs no longer exist.
