These commits change two things:
shebangs of shell scripts
This change also helps other environments that place bash on where else of /bin (such like /usr/bin, /usr/local/bin or in-busybox, wherever). Yes, this change relies on env command being available and placed in /usr/bin, that is confirmed as so on Mac OS, Ubuntu, Arch Linux and FreeBSD.
submodule information of libc-artifacts (to pointing out https://github.com/redox-os/libc-artifacts/pull/7)
This change is as above one but for libc-artifacts submodule; this fix is already pull-requested to the repository, and this change is only for repointing it.
