Preserve given for tool.uv.sources paths (astral-sh#3412)

We now correctly emit relative paths in `uv pip compile` with
`tool.uv.sources` path inputs.

`tool.uv.sources` is mainly intended to be used with the uv lock file
over requirements.txt, but it's good to have basic `uv pip` support
working.

Fixes astral-sh#3366
