[CVE-2012-2123] natty security: fix compile error in commoncap.c

[Steve Conklin]

This is a backport from upstream, Serge pointed out that the earlier CVE
patch causes a failure to build on some architectures, but I didn't run
into it in my testing. This patch should be applied after the previous
one for CVE-2012-2123.
