fix a compile fail by strndup in RHEL5 env

When we compile btrfs-progs in RHEL5(with default gcc 4.1.2 and glibc-2.5-18),
we can get following error:

cc1: warnings being treated as errors
btrfs-list.c: In function 'ino_resolve':
btrfs-list.c:511: warning: implicit declaration of function 'strndup'

make: *** [btrfs-list.o] Error 1

We can add _GNU_SOURCE definition according man strndup.
