[occupancy_map_monitor] add dependencies

[gleichdick]

Description

explicit dependencies to tf2_ros, geometric_shapes and boost are added.
I noticed some linking errors while compiling from source. Applies to master as well

I'm curious about which kind of linking errors you've got. Usually, all those dependencies should be transitively pulled in.

[rhaschke]

There is no specific lib required for boost::function, it's just part of the headers.
This change makes Travis failing.

[rhaschke]

There is no need to explicitly link downstream projects against boost.

The error message was:

I noticed it when I tried to compile moveit from source on Debian Buster. tf2 was from the repo (libtf2-ros-dev 0.6.5-3).
Unfortunately there is right now a dependency issue with catkin on Buster so I could not create a docker container from scratch to reproduce it. However, compiling everything from source (including tf2) without this patch works too.
