Redundant host dependencies

[jcarpent]

Some host dependencies seem redundant in the list:

libsdformat-feedstock/recipe/meta.yaml

Lines 33 to 39 in c9fd784

	- libignition-cmake2
	- libignition-math6
	- libignition-tools1
	- libignition-utils1
	- urdfdom
	- tinyxml2
	- console_bridge

It would be nice to make them minimal I would say. Does it go in line with the whole ROS conda spirit?

Best,
Justin

I think all of the dependencies (except for one, see below) are listed in https://github.com/ignitionrobotics/sdformat/blob/sdf11/cmake/SearchForStuff.cmake and are thus direct dependencies of sdformat. Thus I think it would be risky to remove some of the libignition ones (which indeed might be pulled in transitively).

That said, console_bridge does not seem to be needed anymore and we might want to remove it.
