Update rustix requirement from 0.38.18 to 1.0.3

[dependabot]

Updates the requirements on rustix to permit the latest version.

Changelog

Sourced from rustix's changelog.

Changes from 0.38.x to 1.x

Silent behavior changes

rustix::pipe::fcntl_setpipe_size now returns the new size, which may be greater than the requested size.

When a &mut Vec<_> is passed to rustix::event::epoll::wait, rustix::event::kqueue::kevent, or rustix::event::port::getn, these functions previously adjusted the length of the Vec to the number of elements written, and now do not. A common alternative is to wrap the &mut Vec<_> using spare_capacity, and then to clear the Vec by iterating using .drain(..) after each call. For an example of using spare_capacity in this way, see here.

API changes

rustix::thread::FutexOperation and rustix::thread::futex are removed. Use the functions in the rustix::thread::futex module instead.

rustix::process::waitpid's return type changed from WaitStatus to (Pid, WaitStatus), to additionally return the pid of the child.

terminating_signal and other functions in rustix::process::WaitStatus changed from returning u32 to returning i32, for better compatibility with the new Signal type and exit.

The SLAVE flag in rustix::mount::MountPropagationFlags is renamed to DOWNSTREAM.
