Refactor only change.

Refactor GetFilenames to return internal FileInfo struct which
includes FilePath and FileSystemURL so that it can be reused by
CreateClipboardFilenamesPickle in crrev.com/c/2638967.

By keeping the FileSystemURL in addition to the FilePath, it saves
duplicating the code to crack the URL from the path.
