sstate.bbclass: make sure changes to SSTATE_SCAN_FILES are not ignored

When changing the SSTATE_SCAN_FILES variable in a recipe it doesn't cause a rebuild,
so if there's a sstate-cache available with "bad" sstate data in it that will still
be used even though the recipe is updated to address this.
