Rollup merge of #137759 - joshtriplett:command-chroot, r=Amanieu
Add `std::os::unix::process::CommandExt::chroot` to safely chroot a child process

This adds a `chroot` method to the `CommandExt` extension trait for the
`Command` builder, to set a directory to chroot into. This will chroot
the child process into that directory right before calling chdir for the
`Command`'s working directory.

To avoid allowing a process to have a working directory outside of the
chroot, if the `Command` does not yet have a working directory set,
`chroot` will set its working directory to "/".
