Skip ASN.1 template tests in Windows shared library builds.

This should fix the Chromium roll.

Windows shared library builds are fussy about dllexport vs. dllimport in
a way that's incompatible with external uses of the asn1t.h macros. The
issue is the DECLARE_* macros will add dllexport vs. dllimport on the
assumption the symbols are defined in libcrypto, but external
definitions need a different selector.

Rather than add more complex macros for this, just exclude those tests.
Ideally we wouldn't supoport asn1t.h outside the library at all, if we
can manage it, so no sense in trying to make it work.

This excludes both the new and the old tests. Although this has been
working thus far, it only works because we've been setting the
BORINGSSL_IMPLEMENTATION symbol for test targets wrong in Chromium. I'm
confused how that's been working at all (maybe dllexport vs. dllimport
is more lax when it comes to functions rather than variables?), but when
I do it correctly, the ASN1_LINKED_LIST template breaks too.
