Describe the bug

initNix() clears an environment variable. It shouldn't.

Steps To Reproduce

$ echo TMPDIR=$TMPDIR; nix run nixpkgs#bash -- -c 'echo TMPDIR=$TMPDIR'                                                           ~
TMPDIR=/var/folders/vh/whk9gn015sd7vkh2php03jf80000gn/T/
TMPDIR=

Expected behavior

Darwin:

$ echo TMPDIR=$TMPDIR; nix run nixpkgs#bash -- -c 'echo TMPDIR=$TMPDIR'                                                           ~
TMPDIR=/var/folders/vh/whk9gn015sd7vkh2php03jf80000gn/T/
TMPDIR=/var/folders/vh/whk9gn015sd7vkh2php03jf80000gn/T/

Linux (already works, but the variable isn't even set in my session NixOS):

$ (export TMPDIR=/tmp; echo TMPDIR=$TMPDIR; nix run nixpkgs#bash -- -c 'echo TMPDIR=$TMPDIR')
TMPDIR=/tmp
TMPDIR=/tmp

nix-env --version output

Additional context

Potential duplicate of #395, although the solution hinted here does not have as broad a scope.
