[yocto-autobuilder-helper] oe-mirror: Add job to mirror openembedded sources

- Add a job that call run-fetchuniverse
- Add script run-fetchuniverse
   - loop over each LTS branches
   - Download all the meta-openembedded layers sources.
   - Call to oe-selftest test_yocto_source_mirror after fetching.
We are not using a second step to keep checkout consistency with potential merge.

This needs to be called something like meta-oe-mirror to differentiate
it from other "OE" things.

Rather than iterate here, we should add a configuration to each branch
of -helper where we want to enable this.

Then hopefully we can massively simplify the script!
