topic: further "help pytype" by not mentioning remotebranchcache on hg 4.9

Because it doesn't exist.

This obviously was a real issue on Mercurial 4.9 because we were trying to
directly reference a class that doesn't exist in branchmap module, it wasn't a
string in some typing comment or whatever, so this code previously would not
work on 4.9 at all. Oops!
