siggen: Ensure taskhash mismatches don't override existing data
We recalculate the taskhash to ensure the version we have matches
what we think it should be. When we write out a sigdata file, use
the calculated value so that we don't overwrite any existing file.
This leaves any original taskhash sigdata file intact to allow a
debugging comparison.
