File Browser/BPY: Expose relative path of a file via BPY

There were requests to be able to track the file selection in the File
Browser. Just using the file name for that wouldn't if the file browser
has the recursive display enabled. File names could be duplicated then.
So expose the entire path relative to the currently displayed directory.
