This makes it possible to start _everything_ under UserspaceEmulator, by
setting `init_args` to `--report-to-debug,/bin/SystemServer` and `init`
to `/bin/UserspaceEmulator`.
With the UE patches before this, we get to spawn WindowServer, and crash
because of FLD_RM32 (nothing tested past that) in graphical mode.
But we get a working shell in text mode :^) (and DHCPClient fails when
setting whatever settings it has received)
