windows: allow retrieving true version with RtlGetNtVersionNumbers

While RtlGetVersion was added so that users can get the Windows version
that isn't affected by manifesting, RtlGetVersion is still stubbed out
by the application compatibility layer (aclayers.dll and apphelp.dll)
for certain processes, such as msiexec.exe, rendering these functions
useless for actually determining the underlying operating system. This
matters in the case of msiexec.exe using a custom action DLL to install
a kernel driver, which of course is version specific. This is also
useful, it turns out, for the C runtime library, in which Microsoft uses
this function too. It's existed as a stable interface since Windows XP,
has Wine support, and is used in a decent amount of software.
