build: make install ships the portable image, like every release

A native install cannot leave the machine that compiled it: mux d
upgrade HOST streams the installed image, and the laptop answered a
native build with an illegal instruction. The measured cost of musl is
22ms on the 15MB reattach repaint (92 -> 114 against a 200ms ceiling);
the interactive legs moved inside their noise.
