cFS submodules refer to "master" branches

[CDKnightNASA]

It seems the .gitmodules file still lists "branch = master" for cfe and osal. Should switch to "main". (Surprised "master" still works, given that branch is long gone! Guessing git defaults to "HEAD" if the branch specified no longer exists.)

branch = master

From what I can tell the branch setting in .gitmodules only really matters if you do a git submodule update --remote which isn't really a normal user thing in our flow since the refs you get from the cFS repo gets you something that has gone through the cFS CI. It's a good fix, but shouldn't actually matter unless you are using that command. Not being all that familiar w/ the command above, I typically just use git submodule foreach git checkout main and a corresponding pull.
