23b4356a5f nixos/nixos-*: use runtimeShell
Fix shebangs and other shell uses in the NixOS tools, allowing them to work
correctly on cross-compiled systems.

nixos-enter: redirect to fd2 instead of a file named /dev/stderr
In some cases, /dev/stderr may not point to a sensible location. For
example, running nixos-enter inside a systemd unit where the unit's
StandardOutput and StandardError are set to be sockets. In these
cases, this line would fail.

Piping to fd2 directly works just as well, even under strange and
twisted executions.

Revert "Merge pull request #48122 from zimbatm/pkg-nixos-rebuild"
This reverts commit 10addad603, reversing
changes made to 7786575c6c.

NixOS scripts should be kept in the NixOS source tree, not in
pkgs. Moving them around is just confusing and creates unnecessary
code/history churn.

nixos-*: init as package
Move all the nixos-* scripts from the nixos distribution as real
packages in the pkgs/ package set.

This allows non-nixos users to run the script as well. For example,
deploying a remote machine with:

    nixos-rebuild --target-host root@hostname --build-host root@hostname

14cab1ac57 nixos-enter: Ensures presence of full /sys tree.
This partially reverts a change from e88f28965a
which removed the `mount --rbind /sys`.

While true that the activation scripts will mount `sysfs` at `/sys`,
none of the mountpoints lower in the `/sys` tree are handled by the
activation script, which includes `efivarfs`.

This fixes #38477 since it ensures the presence of `efivarfs` in the
`/sys` tree, which is why the systemd-boot installation failed.

nixos-enter: Don't mount special filesystems
The activation script already does this.

Add a "nixos-enter" command
This factors out the functionality in nixos-install for running a
command inside a NixOS installation (nixos-install --chroot).
