Mauri de Souza Meneguzzo ad02017442 windows: use SyscallN in mkwinsyscall 
The mkwinsyscall command has a hard limit of 15 on the
number of syscall arguments. Windows has several system
calls with more than 15 arguments, for example CreateFontPackage
has 18 arguments.

If the number of arguments is higher than 15 we use SyscallN.

Fixes golang/go#57914

Mauri de Souza Meneguzzo 25d0004552 unix: fix last argument of pselect6 on linux 
On Linux, the last argument of pselect6 system call is **not** a
sigseg_t * pointer, but instead it is a structure of the form:

    struct {
        const sigset_t *ss;     /* Pointer to signal set */
        size_t          ss_len; /* Size (in bytes) of object pointed
    };

See man 2 pselect6.

Fixes #61251
