feature: add duckdb driver to base drivers

[l1t1]

it's more convenient to use.

@l1t1 DuckDB is already in usql, unfortunately it can't, at this time, be made a base driver because it isn't available "out of the box" on Windows. In fact, DuckDB is disabled on Windows builds at the moment, as the Go driver doesn't have binaries available for it.

Windows binary was added to go-duckdb since - marcboeker/go-duckdb#248 . I tried it and it seems to work:

I think the windows part of the no_duckdb rule can be removed from build.sh. However, IMO, duckdb still doesn't belong in base, because go install github.com/xo/usql@latest will fail on systems without gcc and build tools.
