[LTP] [PATCH] lib/tst_tmpdir.c: fix compilation with older kernels

[Xiao Yang]

Compilation fails because of undefined __USE_GNU on RHEL5.11GA.
So we need to define _GNU_SOURCE to make __USE_GNU defined.

This has been broken by commmit:

Good catch. I've updated the changelog, since the problem is about older
libc not kernel and pushed along with a few more typo fixed I've done
yesterday.
