run-make: enable msvc for staticlib-dylib-linkage

`-Zstaticlib-allow-rdylib-deps` on MSVC returns things like `/LIBPATH:R:\rust\build\x86_64-pc-windows-msvc\test\run-make\staticlib-dylib-linkage\rmake_out`. That is a linker argument rather than a `cc` argument. Which makes sense because rustc interacts directly with the linker on MSVC targets. So we need to tell the C compiler to pass on the arguments to the linker.
