nix develop: Ignore stdenv's $SHELL

Browse source 
Stdenv sets this to a bash that doesn't have readline/completion
support, so running 'nix (develop|shell)' inside a 'nix develop' gives
you a crippled shell. So let's just ignore the derivation's $SHELL.

This could break interactive use of build phases that use $SHELL, but
they appear to be fairly rare.
