Add the stable release candidate repo to the Linux git repos menu

I have several nightly test runners that pull LTS release candidates
for testing. I have to hand-edit the Kconfig for each test runner
when switching from the master repo to a local mirror.

I would like to get those to switch automatically over
to using a local mirror, when one is available.
