Rollup merge of #46421 - mnd:fix-build-for-guix, r=alexcrichton
build_helper: destination file can't be up to date when not exists

Function "up_to_date" return incorrect result if mtime for all fetched sources is set to epoch time. Add existence check to function.

This fix required for a [Guix](https://www.gnu.org/software/guix/) package because a Nix builder set mtime of all sources to epoch time.
