## Message

```
linux.zig: epoll_wait: pass kernel sigset size

Linux kernel syscalls expect to be given the number of bits of sigset that
they're built for, not the full 1024-bit sigsets that glibc supports.

I audited the other syscalls in here that use `sigset_t` and they're all
using `NSIG / 8`.

Fixes #12715
