Change this to a preprocessor check.

Obviously this needs to happen at the preprocessor level because
SSLVersionRange won't exist in old versions. I'm not sure when
these constants started appearing... I'm kinda just hoping they've
been around as long as the NSS_VersionCheck function (NSS 3.2, I think,
which was many years ago). I might look into it. But checking this
in now to get in before the nightly Jenkins build for ppc.

HOWTOs in the "Related Pages" section.
You can also generate this documentation locally by installing
doxygen and graphviz dot, then running "make docs" in the
source tree. The documentation will be in the docs/html directory.
