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

Browse Source 
If O_PATH is set, then the fhandler_fifo object has a handle that can
be used for getting the statvfs information.  Use it by calling
fhandler_base::fstatvfs_by_handle.  Before this change,
fhandler_disk_file::fstatfvs was called on a new fhandler_disk_file
object, which would then have to be opened.
