Make `.rmeta` file in `dep-info` have correct name (`lib` prefix)

Since `filename_for_metadata()` and
`OutputFilenames::path(OutputType::Metadata)` had different logic for
the name of the metadata file, the `.d` file contained a file name
different from the actual name used. Share the logic to fix the
out-of-sync name.

Closes 68839.
