unix: fix Pause on linux-arm64

Pause is a legacy syscall not available on linux-arm64. Use ppoll with
all args as 0 to emulate - this is the way musl libc does Pause when the
pause syscall isn't available.

With the changes in syscall_linux* and regenerating zsyscall_linux*,
this calling Pause on linux-arm64 works and returns EINTR as expected.
