bitbake: siggen: Fix type conversion issues

Browse Source 
The switch to using json has messed up the type handling as the code
does assume that set()s are present. Add a decoder to reconstruct
the set() objects. Also fix the change of tuples to lists for the
file checksums and fix an existing type bug where dicts insteads of
lists was used.

Drop some old siginfo format handling code which is now long since
obsolete.
