linux-yocto: apply meta data to external repos

To support quick uprev and testing, it is desireable to build
repositories that do not have embedded meta data. In this scenario
the meta data can be automatically created or provided externally.
This commit supports the first situation by detecting the lack
of meta data and then automatically creating a base set of meta
files.
