sstatesig: Improve to handle locking of multiple machines

Instead of a single monolithic SIGGEN_LOCKEDSIGS, split this into
separate variables, one per sstate package architecture. Add in
a new SIGGEN_LOCKEDSIGS_TYPES variable which lists the package
architectures to load in.

SIGGEN_LOCKEDSIGS_TYPES is made machine specific using overrides.

Also sort the hashes in the lists by PN to make diffing them easier.
