This fix "touch" a file above gvfs sftp and enable to use rsync (though
with perms=0).

The fact that rsync needs a perms hacks I leave for another patch (if I
manage to fix it). As the chmod works this is likely a problem with
getattr opcode ...

This is my first attempt to send an inline patch from this station (the
setting are likely not correct) so I also send it as attachment .

[PATCH] Add support for utimens in gvfs sftp backend.

This fixes "touch" a file and help with rsync (one still needs the perms=0 
hack).
