This prevent the build from failing with "Error: TEMPLATECONF
value (which is coreos/templates) must point to
meta-some-layer/conf/templates/template-name" when sourcing
coreos-init-buildenv with OE-Core Master.
To make images compatible with each other for development a comon set of keys
will be used. The keys are located on k-stufen.
* add script to download and extract keys
* adjustments to coreos-init-build-env script
* adjustments to check_files_exist function
