Update github.com git:// SRC_URIs

Update github.com git:// SRC_URIs

GitHub is dropping unauthenticated git protocol access in
January 2022, per:

https://github.blog/2021-09-01-improving-git-protocol-security-github/#no-more-unauthenticated-git

While a workaround in the BitBake git fetcher is forthcoming, not
specifying protocol=https for github.com git:// SRC_URIs will start
resulting in warnings in Yocto 3.5/Kirkstone.  To ease our upgrade
path, go ahead and update our affected SRC_URIs.  Note that this has
been done by running the scripts/contrib/convert-srcuri.py script
from latest poky, which also makes git branch specification explicit
since the git fetcher is likely to require that in the future due
to widespread switches from master to main branches.
