Add branch rename workarounds

Add bbappends for ndctl and ttf-noto-emoji recipes to tweak their
SRC_URIs to handle their upstreams renaming the "master" branch to
"main".  This works around the resulting build failures that would
happen otherwise, and patches will be submitted for meta-openembedded
so we can hopefully drop these on the next set of layer updates.
