bug#25983: 25.2; set dired-directory in vc-dir mode

[Tom Tromey <tom@tromey.com>]

I'd find it handy if vc-dir buffers had dired-directory set.
This can serve as an indication that the buffer is associated with some
directory, even though it's not visiting a file.

I've appended the patch I would like to apply.
Let me know what you think.

Tom
