fix type of extended argument array to pselect6 syscall
this only matters on x32 (and perhaps future 32-on-64 abis for other archs); otherwise the type is long anyway. the cast through uintptr_t prevents nonsensical "sign extension" of pointers, and follows the principle that uintptr_t is the canonical integer type to which pointer conversion is safe.
