grantpt.3: SYNOPSIS: Explicitly show #define _XOPEN_SOURCE requirement

Like the unlockpt(3) function, grantpt(3) requires _XOPEN_SOURCE to be
defined before including stdlib.h.

unlockpt.3 explicitly shows this requirement in its SYNOPSIS:

    SYNOPSIS
           #define _XOPEN_SOURCE
           #include <stdlib.h>

           int unlockpt(int fd);

But grantpt.3 did not:

    SYNOPSIS
           #include <stdlib.h>

           int grantpt(int fd);
