chroot fails to load init

[fulalas]

Steps to replicate

1. try to boot any sysvinit distro
2. initrd fails when calling exec bin/chroot / /mnt/live/bin/init

Just by changing chroot to GNU one and keeping everything else untouched, the system boots just fine:

System
PorteuX 2.4 dev
coreutils 0.3.0 built using cargo build --release --features unix

coreutils/src/uu/chroot/src/chroot.rs

Line 213 in 686127c

let pstatus = match process::Command::new(chroot_command)

I think this code is probably the problem.
