yocto-builder/entrypoint-build.sh: Replace Poky

Following the recent major breaking change with the introduction of
bitbake-setup because of which the Poky repository master branch is
no longer being updated, the Poky git repository has to be replaced
by bitbake, openembedded-core and meta-yocto which provides layers
meta-poky and meta-yocto-bsp. This fixes the GitHub workflows with
branch master of meta-raspberrypi and allows running auto checks.

This work was sponsored by GOVCERT.LU.
