emacs: Clear the environment while dumping This reduces the closure size of Emacs from 575 to 279 MiB. Dumping Emacs had a chance of leaking parts of the environment (such as $PATH) into the dumped executable. This hopefully fixes it. (It's a bit hard to tell since the effect is not deterministic.)

Dump temacs in an empty environment to prevent -dev paths from ending
