sign.cpp: turn on SIGHASH_SCRIPT_RANGEPROOF when checking already-existing signatures

Browse source 
Currently when a user uses `signrawtransaction` on a transaction that is
already partially signed with SIGHASH_RANGEPROOF signatures, the existing
signatures will be deleted because they are not recognized as valid. This
makes it impossible to collabratively sign transactions using this RPC.
Fix this.
