If the file descriptor references a file outside the chroot, then calling
readlink on that file descriptor's entry in /proc/self/fd/<n> returns the
full path, even though that path does not exist in the chroot.
This tests the opposite case from ChrootTest.ProcMemSelfFdsNoEscapeProcOpen,
which tests what path is returned when the file is inside the chroot.
