Auto merge of #84716 - joshtriplett:chroot, r=dtolnay

Add std::os::unix::fs::chroot to change the root directory of the current process

This is a straightforward wrapper that uses the existing helpers for C
string handling and errno handling.

Having this available is convenient for UNIX utility programs written in
Rust, and avoids having to call the unsafe `libc::chroot` directly and
handle errors manually, in a program that may otherwise be entirely safe
code.
