    sim: ppc: fix Wnonnull warning
    
    When compiling with --enable-werror and CFLAGS="-O0 -g -Wall", we run into:
    ...
    src/sim/ppc/emul_netbsd.c: In function 'do_gettimeofday':
    src/sim/ppc/emul_netbsd.c:770:16: error: null argument where non-null \
      required (argument 1) [-Werror=nonnull]
       int status = gettimeofday((t_addr != 0 ? &t : NULL),
                    ^~~~~~~~~~~~
    ...
    
    Fix this by unconditionally passing &t as first argument.
