util/cacheinfo: Add missing include for ppc linux

This include was forgotten when splitting cacheinfo.c out of
tcg/ppc/tcg-target.inc.c (see commit b255b2c8).

For a Centos7 host, the include path

<signal.h>
<bits/sigcontext.h>
<asm/sigcontext.h>
<asm/elf.h>
<asm/auxvec.h>

implicitly pulls in the desired AT_* defines.
Not so for Debian Jessie.
