nVersion fuzz format changes

[maflcko]

Similar to #159

Transform the inputs after the format change in bitcoin/bitcoin@fa7eb4f

Done by nuking the first 4 bytes with:

for f in ./block/*        ; do python -c "fn=\"$f\"; print(fn); open(fn+'.new', 'wb').write(open(fn,'rb').read()[4:]);" ; done 
for f in ./transaction/*  ; do python -c "fn=\"$f\"; print(fn); open(fn+'.new', 'wb').write(open(fn,'rb').read()[4:]);" ; done 
for f in ./*_deserialize/*; do python -c "fn=\"$f\"; print(fn); open(fn+'.new', 'wb').write(open(fn,'rb').read()[4:]);" ; done
