r462630 added OpenSSL include/library paths to CFLAGS/LIBS which caused
the _elementtree and pyexpat modules to fail to build. Adding paths to CFLAGS
is known to cause issues [1].
Accordingly:
- Switch to using CPPFLAGS for OpenSSL include/library paths (like NLS).
- Move the comment describing why this is necessary to the top of the port
with reasonable warning about what can happen and why.
