[build][assembly] Only allow the fuchsia toolchian in //build/images

Stumbled across this by accident.  This change adds an assert that the
//build/images/BUILD.gn file is only processed in the Fuchsia toolchain,
not the host (or any other variant), as well as correcting the one place
that was causing it to be processed in the host toolchain.
