ff4a38a32766942ce5c4be6d6510f800a9f8e0d9 build: Fix configuring depends with cmake (Hennadii Stepanov)

Pull request description:

  This PR fixes bitcoin/bitcoin#24389.

  On master (28aa0e3ca0a6cfeb5b2b63929d4bc58de6ee6f02) configuring of the `libmultiprocess` package for the `x86_64-w64-mingw32` target fails:
  ```
  $ cd depends
  $ make libmultiprocess_configured MULTIPROCESS=1 HOST=x86_64-w64-mingw32
  Configuring libmultiprocess...
  CMake Warning:
    No source or binary directory provided.  Both will be assumed to be the
    same as the current working directory, but note that this warning will
    become a fatal error in future CMake releases.

    is not able to compile a simple test program.

    It fails with the following output:

  ```

  The reason of that failure is the unset `-DCMAKE_SYSTEM_NAME` flag:
  ```
  $ make print-libmultiprocess_cmake MULTIPROCESS=1 HOST=x86_64-w64-mingw32
  libmultiprocess_cmake=env CC="x86_64-w64-mingw32-gcc" CFLAGS="  -I/home/hebasto/GitHub/bitcoin/depends/x86_64-w64-mingw32/include     -pipe -O2    " CXX="x86_64-w64-mingw32-g++-posix" CXXFLAGS="  -I/home/hebasto/GitHub/bitcoin/depends/x86_64-w64-mingw32/include     -pipe -O2    " LDFLAGS="  -L/home/hebasto/GitHub/bitcoin/depends/x86_64-w64-mingw32/lib    " cmake -DCMAKE_INSTALL_PREFIX:PATH="/home/hebasto/GitHub/bitcoin/depends/x86_64-w64-mingw32" -DCMAKE_SYSTEM_NAME= -DCMAKE_C_COMPILER_TARGET=x86_64-w64-mingw32 -DCMAKE_CXX_COMPILER_TARGET=x86_64-w64-mingw32
  ```

  This PR fixes this error:
  ```
  $ make libmultiprocess_configured MULTIPROCESS=1 HOST=x86_64-w64-mingw32
  $ # no errors
  ```
