tests/lib/params-cm.h: allocate enough storage for the D-Bus representation of int16/int32

Even though the D-Bus types are 16 and 32 bits respectively, we store them
in the struct as gint/guint, following the usual dbus-glib convention.

On architectures like i386 that pad 16-bit struct members to 32 bits
and are little-endian, we happen to get away with it, but on powerpc we don't.
