sslutil: clarify internal documentation

I ran into this python issue with an incomplete certificate chain on Windows
recently, and this is the clarification that came from that experimenting.  The
comment I left on the bug tracker [1] with a reference to the CPython code [2]
indicates that the original problem I had is a different bug, but happened to
be mentioned under issue20916 on the Python bug tracker.
