Add transitive dependenty for map_msgs

[esteve]

Builds for downstream packages fail beacause the map_msgs package is exported as a dependency in CMakeLists.txt, but is not declared as a dependency in package.xml

This is the error we're getting:

If this is also a runtime dependency, why did you only use build_export_depend?

[esteve]

@Ryanf55 map_msgs doesn't seem to be a runtime dependency, in fact, it's not used anywhere, so I wonder why it's declared as an export dependency here:

grid_map/grid_map_rviz_plugin/CMakeLists.txt

Lines 135 to 142 in c313843

	ament_export_dependencies(
	Qt5
	rviz_common
	geometry_msgs
	map_msgs
	nav_msgs
	rclcpp
	)

Might as well be removed from the ament_export_dependencies list.
