Subject: [PATCH] MSVC: Do not build in library form

Library form overwrites module form due to both having the same name `gost.dll'.
As temporary workaround do not build library form on Windows, until we invent
how to solve it properly. Currently, there is no known need of engine in the
library form on Windows.
