[OE-core] [PATCH 3/3] util-linux-native: Remove SYS_setns system call in linux kernel 2.6.x

[Kai Kang]

From: "yanjun.zhu" <yanjun.zhu at windriver.com>

__NR_setns is not defined in linux kernel 2.6.x. To linux kernel 3.0,
this variable is defined. It has been shown that no native tools use
this syscall, so it is safe to make this substitution
