cheri: change __libc_start_main prototype

The prototype of __libc_start_main is changed to

  void
  __libc_start_main (int main (int, char **, char **, void *),
                     int argc, char **argv, char **envp, void *auxv,
                     void rtld_fini (void), void *sp);

so envp is passed down separately and the unused init, fini args are
dropped.
