siggen.py: fix the wrong usage on BB_TASKHASH_WHITELIST

BB_TASKHASH_WHITELIST is expected to filter out native tasks from the
dependency list for target recipe's checksum. However current code
actually implements the opposite. All native sstate packages end up
to have empty task dependency while target sstate packages still have
native tasks counted into the checksum.
