lib/oe: Add sstatesig, OE specific signature generator classes
This patch adds SignatureGenerator classes specific to OE. For now, these emulate the previous behaviour with the exception that dependencies on quilt-native are now ignored for checksum purposes. The intent is to allow easier experimentation and customisation of this code in future as a result of these changes. Note that these changes require pending bitbake patches.
