hector_map_tools: Use the FindEigen3.cmake module provided by Eigen
This patch applies the recommendation from http://wiki.ros.org/jade/Migration and removes the
dependency from package cmake_modules (unless your installation of Eigen3 does not provide a
cmake config).
Same as 1251d9dc20854f48da116eed25780c103a5bd003, but package hector_map_tools was not updated
back then.
