Subject: Remove the patch CP feature (Bug #5594)

This "feature" has been broken for almost a year without anyone noticing; see https://redmine.pfsense.org/issues/5594 for details. Remove this junk until a saner alternative is available. System Patches is the way to go until that happens if someone really requires that.

On upgrade, an attempt to restore a backup will be attempted, and appropriate notice filed (and logged). There are also GUI instructions left in place of the original checkbox.
