[oe] [PATCH v2] lmbench: Fix compilation error of gcc format-security

[zhe.he at windriver.com]

From: He Zhe <zhe.he at windriver.com>

oe-core "security_flags: turn potential string format security issues
into an error" adds "-Wformat -Wformat-security -Werror=format-security"
to the default SECURITY_CFLAGS, which may cause lmbench compilation
failure.

This patch fixes lmbench's code.
