move types.hpp to ipmid/types.hpp for export

types.hpp is required by utility.hpp, which is exported, so it needs to
be exported as well. This moves it to the include/libipmid directory,
changes the Makefile to export it, and changes all the files that
include it so it can be found in the right place.
