Format 2 and build_export_depend orocos kdl

[sloretz]

Switch to format to in order to <build_export_depend>liborocos-kdl-dev</build_export_depend> in packages which export the dependency in their CMakelists.txt

Should fix this error

Test failure in tf.lookupTransform_ring45. It seems unlikely to be related to this PR, though I don't see it in the latest geometry dev job.

The test failure looks like it might be related to: https://github.com/ros/geometry2/pull/459/commits/6e505b1cfc16af860e970f010873afa9902af36f

Could be. Definitely unrelated to this PR; I also get the test failure locally using the noetic-devel branch.
