Handle relative file names in vc-resynch-window and vc-resynch-buffer

* lisp/vc/vc-dispatcher.el (vc-resynch-window, vc-resynch-buffer):
While comparing with `buffer-file-name' if `file' is not absolute
use `expand-file-name' in `vc-root-dir'.  This fixes the case of
refreshing the buffers after typing `C-x v = C-x v u' (bug#60897).
