INSTALL: Advise use of non-native SSL for Windows <= XP

Advise that WinSSL in versions <= XP will not be able to connect to
servers that no longer support the legacy handshakes and algorithms used
by those versions, and to use an alternate backend like OpenSSL instead.

Legacy Windows and SSL
======================
Some of the project configurations use as an SSL backend WinSSL (Windows SSPI,
more specifically Schannel), the native SSL library that comes with the Windows
OS. WinSSL in Windows <= XP is not able to connect to servers that no longer
support the legacy handshakes and algorithms used by those versions. If you
will be using curl in one of those earlier versions of Windows you should
choose another SSL backend like OpenSSL.
