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
up in the dumped image.
