Revert setup of data files on Windows

We are only interested in bundling the DLL file for GEOS on Windows
for standard installations but not for MinGW64 or Cygwin. Therefore,
the filename pattern matching needs to be more restrictive because
otherwise we will find `libgeos_c.dll` as valid file to bundle.
