fix: run fix-python-soname.js from npm package directory in Linux tests

The fix-python-soname.js script patches the .node file in its __dirname.
When run from root, it patches the root .node file (which doesn't exist
in Docker tests). We need to run it from the npm package directory to
patch the binary that will actually be loaded via pnpm link.
