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.
