    ada: Fix Ada bootstrap on macOS
    
    The recent warning changes broke Ada bootstrap on macOS:
    
    adaint.c: In function '__gnat_copy_attribs':
    adaint.c:3336:10: error: implicit declaration of function 'utimes'; did you
    mean 'utime'? [-Wimplicit-function-declaration]
     3336 |      if (utimes (to, tbuf) == -1) {
          |          ^~~~~~
          |          utime
    adaint.c: In function '__gnat_kill':
    adaint.c:3597:3: error: implicit declaration of function 'kill'
    [-Wimplicit-function-declaration]
     3597 |   kill (pid, sig);
          |   ^~~~
    terminals.c: In function 'allocate_pty_desc':
    terminals.c:1196:12: error: implicit declaration of function 'openpty'; did
    you mean 'openat'? [-Wimplicit-function-declaration]
     1196 |   status = openpty (&master_fd, &slave_fd, NULL, NULL, NULL);
          |            ^~~~~~~
          |            openat
    terminals.c: In function '__gnat_setup_winsize':
    terminals.c:1392:6: error: implicit declaration of function 'kill'
    [-Wimplicit-function-declaration]
     1392 |      kill (desc->child_pid, SIGWINCH);
          |      ^~~~
    
    This patch fixes this by including the necessary headers: <sys/time.h>
    for utimes, <signal.h> for kill, and <util.h> for openpty.  With those
    changes, the build completed on x86_64-apple-darwin2[0-3] (make check
    still running).

            gcc/ada:
            * adaint.c [__APPLE__]: Include <signal.h>, <sys/time.h>.
            * terminals.c [!_WIN32]: Include <signal.h>.
            [__APPLE__]: Include <util.h>.
            Fix typos.
