Enable an alternative swupd certificate location (the location of the default or given cert with an ".alt" appended to it). The purpose of this change is to allow more reliable and flexible key rotations.
If either the main cert or alt cert fails when doing content verification then the other will be tried (and be used for the next operation). In this way, as long as both certs don't fail for the same content verification, progress can be made with either cert.
