nix-shell: Fix $PATH handling in the impure case
...
We were passing "p=$PATH" rather than "p=$PATH;", resulting in some
invalid shell code.
Also, construct a separate environment for the child rather than
overwriting the parent's.

Fix early removal of rc-file for nix-shell
...
BASH_ENV causes all non-interactive shells called via eg. /etc/bashrc to
remove the rc-file before the main shell gets to run it. Completion
scripts will often do this. Fixes #976 .
Adapted from and fixes #1034 .

nix-build: Port to c++
...
This was a dumb line-for-line rewrite, because nix build/nix run/etc.
will replace it.
