Subject: liblzma: Use _MSVC_LANG to detect when "noexcept" can be used with
 MSVC.

By default, MSVC always sets __cplusplus to 199711L. The real
C++ standard version is available in _MSVC_LANG (or one could
use /Zc:__cplusplus to set __cplusplus correctly).

Fixes <https://sourceforge.net/p/lzmautils/discussion/708858/thread/f6bc3b108a/>.

Thanks to Dan Weiss.
