Jon Griffiths 572942c783 psbt: use DER encoded + sighash byte for PSBT_IN_PARTIAL_SIG items
Per BIP-0171, the signature map is of pubkey to "The signature as would
be pushed to the stack from a scriptSig or witness".

Fixes 5298

Changelog-Fixed: PSBT: Fix signature encoding to comply with BIP-0171.
