sstatesig: introduce SignatureGeneratorOEBasicHashLite

* Rebuilds packages when:
  a) If you edit patches of a given recipe it will rebuild.
  b) If you change a task like do_configure, things after it will rerun in
     a given recipe.
  c) If a dependent task in another recipe changes, it won't rerun.
  d) If you change some global configuration variable or shared .bbclass
     it will rebuild.
