build: Assume the soname is <library>.dll when building for MinGW hosts.

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.
