BIP 0174: Clarify use of PSBT_IN_FINAL_* when data is empty

This is a clarification on how PSBT_IN_FINAL_SCRIPTSIG and PSBT_IN_FINAL_SCRIPTWITNESS should be handled when the data is empty. Based on feedback from @achow101 on twitter https://twitter.com/kallerosenbaum/status/1443856371368271872 It seems [more people than I](https://twitter.com/benthecarman/status/1443858125971501057?s=20) had interpreted the bip like you should always set PSBT_IN_FINAL_* even if data is empty, but @achow101 says we should leave those unset.
