[nautilus-open-terminal] Only allow to open local terminal for remote URIs if a ~/.gvfs mapping exists

[Christian Neumair <cneumair src gnome org>]

commit 10fb3df722febc6a6433a06b84ac315609d9e7ee

    Only allow to open local terminal for remote URIs if a ~/.gvfs mapping exists
    
    If GVFS has not been compiled with FUSE support, there exists no ~/.gvfs back-mapping of remote URIs.
    Nevertheless, we displayed the possibility to open a local terminal in the corresponding ~/.gvfs path.
    This patch introduces a checking routine that determines whether an URI can be mapped to a local path
    before showing the local terminal options.
