[PATCH vkd3d 1/5] build: Assume the soname is <library>.dll when building for MinGW hosts.

[Henri Verbeet]

That's not strictly true, but the only case we care about is the Vulkan
DLL on Windows, for which the official import library is called
vulkan-1.lib, and the DLL is called vulkan-1.dll. We can do something
more elaborate once it becomes relevant.
