getdents has been deprecated since linux 2.4 and newer arches (arm64) might no longer provide the getdents syscall. Use getdents64 for reading the /proc/self/fd/ dir so --track-fds=yes works reliable on all arches. Without this the none/tests/fdleak*vgtest might fail. git-svn-id: svn://svn.valgrind.org/valgrind/trunk@14384
