[PATCH] adjust parisc sys_ptrace prototype

Make the pid argument a long as on every other arcihtecture.  Despite pid_t
beeing a 32bit type even on 64bit parisc this is not an ABI change due to
the parisc calling conventions.  And even if it did it wouldn't matter too
much because 64bit userspace on parisc is in an embrionic stage.
