[OE-core] [PATCH 4/6] qemuwrapper-cross: always fall back to x86_64 and i386 variants of qemu

This helps in particular when executing nativesdk- postinsts; previously
they were attempted only with target qemu, and this obivously failed.
This could be solved by properly mapping the binary to be run to the
best available qemu variant for the binary architecture, but that
would be a lot more invasive change, and so I think a simple fallback
should be fine.
Also, add 'set -x' so we know exactly what is being executed.
