[LTP] [PATCH] controllers/cpuset_lib: Fix compiler error

[Petr Vorel]

Hi Xiao,

> Before glibc 2.19, _DEFAULT_SOURCE wasn't added and led to compiler error.
> We replace _BSD_SOURCE, _XOPEN_SOURCE and _DEFAULT_SOURCE with _GNU_SOURCE.

Thanks for fixing, pushed!
I should have checked it and tested it on old distros myself.
