Sourcemap for local files is absolute path

[shgysk8zer0]

Describe the bug
If scripts use import.meta and are local files, the soucemap contains the absolute filepath.
e.g. /home/${username}/Projects/${project}/${path}

To Reproduce
Steps to reproduce the behavior:

1. Use import.meta.url or import.meta.resolve() in a local script
2. Run rollup with rollupImport() and rollupImportMeta()
3. Open in a browser
4. See sources/Debugger panel

Expected behavior
The source should not be file://...

Additional context
Need to get back the original id or something, not use the transformed id
