[Linux] Add submodules to cross-build libmonodroid for Windows (#1729)
Adds two components that are required by libmonodroid but not provided with the packaged mingw on Linux (they are part of the MXE build on macOS): * `dlfcn-win32`: `dlopen()` + friends for Windows * `mman-win32`: `mman.h` (`mmap()` and friends) for Windows This helps allows us to perform a full build of Xamarin.Android with cross build for Windows on Linux.
