exec isn't needed anymore, so I thought I may as well simplify the code (since it's not being used for --phase either). Before, it was necessary for exiting the then-interactive shell.

I don't have a strong opinion on this, but it seems cleaner to keep it, if only to avoid having a useless bash process lying around while the command is running

However, this currently breaks because of
nix develop's use of--rcfile: the stdin is executed by the shell instead of being passed to the-ccommand. Not using--rcfilewith-c, just like it's already being done with--phase, fixes this.
