  Add includes for stdlib.h, string.h and unistd.h. This resolves below
GCC errors:

  cygmon-gmon.c: In function 'monstartup':
  cygmon-gmon.c:109:21: error: implicit declaration of function 'sbrk' [-Wimplicit-function-declaration]
    109 |   buffer = (char *) sbrk (monsize);
        |                     ^~~~
  cygmon-gmon.c:112:7: error: implicit declaration of function 'write'; did you mean 'fwrite'? [-Wimplicit-function-declaration]
    112 |       write (2, MSG , sizeof(MSG));
        |       ^~~~~
        |       fwrite
  cygmon-gmon.c:115:3: error: implicit declaration of function 'bzero' [-Wimplicit-function-declaration]
    115 |   bzero (buffer, monsize);
        |   ^~~~~
  cygmon-gmon.c: In function '_mcount':
  cygmon-gmon.c:224:7: error: implicit declaration of function 'atexit' [-Wimplicit-function-declaration]
    224 |       atexit(_mcleanup);
        |       ^~~~~~
  cygmon-gmon.c:66:1: note: 'atexit' is defined in header '<stdlib.h>'; this is probably fixable by adding '#include <stdlib.h>'
     65 | #include "cygmon-gmon.h"
    +++ |+#include <stdlib.h>
