net/uriparser: Improve and simplify port
- Simplify DOCS option and move DOCS_DISTFILES to main port (this also prevents unintentional mismatches during updates)
- Align port Makefile layout with majority of ports in tree
- Remove unneeded build dependency of bash
- Don't install docs from main release archive, RFCs should be fetched and txt file is unprocessed
- Replace cmake:noninja with cmake as it builds fine
