bitbake: cooker/siggen: Reset siggen when reparsing

If we don't do this, we get basehash mismatch errors occurring from the reparse
which would then set bitbake's error exit code.

This for example would cause oe-selftest -r bbtests.BitbakeTests.test_bbappend_order
to fail with a non-zero BB_SERVER_TIMEOUT.
