[PATCH] automation: Switch yocto-qemux86-64 job to run on x86

[Michal Orzel <michal.orzel@xxxxxxx>]

At the moment, all Yocto jobs run on Arm64 runners. To address CI
capacity issues, move yocto-qemux86-64 job to x86. Reflect the change in
the makefile generating Yocto docker files and fix CONTAINER name
definition that incorrectly expects YOCTO_HOST variable to be set for x86
container as well, which does not have a platform name appended.

Signed-off-by: Michal Orzel <michal.orzel@xxxxxxx>

I built and pushed a new container to registry.
