Now that nixUnstable supports remounting in the "/nix/store is a
mountpoint" case, this is no longer necessary.
This reverts commit f1d48aec43.

In principle this could work, but the current remount logic in nix fails
to remount mountpoints that are root in their own filesystem (as would
be the case with bind-mounting a mountpoint over itself). nixos/nix#98
is aimed at fixing this.
