[libvirt] [PATCH] Include param.h in case of HAVE_BSD_CPU_AFFINITY

[Guido Günther]

This fixes compilation on kFreeBSD which otherwise fails like

  CC       util/libvirt_util_la-virprocess.lo
In file included from /usr/include/sys/cpuset.h:35:0,
                 from util/virprocess.c:43:
/usr/include/sys/_cpuset.h:49:43: error: 'NBBY' undeclared here (not in

  long __bits[howmany(CPU_SETSIZE, _NCPUBITS)];

                                          ^
/usr/include/sys/cpuset.h:218:48: error: expected ')' before 'id_t'
 int cpuset_getaffinity(cpulevel_t, cpuwhich_t, id_t, size_t, cpuset_t
*);
                                                ^

 int cpuset_setaffinity(cpulevel_t, cpuwhich_t, id_t, size_t, const
cpuset_t *);

And it's the correct usage as documented in
