Cygwin: AF_LOCAL::fstatvfs: use our handle if O_PATH is set

Browse Source 
If O_PATH is set, then the fhandler_socket_local object has a handle
that can be used for getting the statvfs information.  Use it by
calling fhandler_base::fstatvfs_by_handle.  Without this change,
fhandler_disk_file::fstatfvs would be called on a new fhandler_disk
object, which would then have to be opened.
