databases/lua-lsqlite3: unbreak the build against non-amalgamated SQLite

• Change the :target in SQLite dependency to build' so that files which are copied during pre-configure' stage would be generated;
• Don't explicitly list supported Lua versions in the COMMENT and define options after other declarative knobs and before targets;
• Switch to the new upstream distfile (version remained the same) as the previous one is no longer fetchable. Looking at the changes, they span the period from 2018-07-01 to 2021-09-07 and look legit. Also, the test suite had been amended; it would be hooked in another commit.
