Make handling of cross-platform emulation for static builds smarter. ()

Browse source 
* Switch to tonistiigi/binfmt for cross-build emulation.

It’s actually being actively updated, and it also supports hosts other
than x86-64.

* Auto-detect existing QEMU user emulation in static build.

Instead of relying on the user to explicitly ask for no emulation.
