Support non-ASCII source artifact paths on UNIX platforms.

Fixes https://github.com/bazelbuild/bazel/issues/7255, and mitigates some of the most annoying limitations of https://github.com/bazelbuild/bazel/issues/374.

Summary: On UNIX platforms, Bazel uses `readdir()` via `NativePosixFiles` but opens paths with `java.io.File`. These two libraries use different representations of non-ASCII filesystem paths, which prevents Bazel from reading source artifacts.

There is a workaround, because `java.io.File` can also accept the path as a `URI` with percent-encoded octets. Using this mechanism for paths containing characters outside the ASCII range allows Bazel to happily consume source artifacts with Unicode filenames.
