Don't provide the cmake files any more
- Don't provide the cmake files any more as they are broken and cmake
itself already provides its own boost detection mechanism.
Should fix detection of boost by mingw32-qpid-cpp. RHBZ #597020, RHBZ #789399
- Added patch which makes boost install dll's to %{_mingw32_bindir}
instead of %{_mingw32_libdir}. The hack in the %install section
to manually move the dll's is dropped now
