ROS buildfarm uses ccache while Drake refuse to be built with it

[j-rivero]

Mainly with issues described and linked to RobotLocomotion/drake#4464, current Drake version 1.25.0 can not be built with ccache.

The ROS 2 buildfarm uses ccache binaries although the compilation artifacts sharing is not actually in use, so I we can probably workaround the problem by removing the ccache binaries from the build package process, see ros-infrastructure/ros_buildfarm#1021.

I'm of course fine with avoiding installing packages that aren't used.

In case they ever do get installed again in the build farm, I think the work-around for Drake is as simple as removing /usr/lib/ccache from $PATH before running the Drake build step -- or at least before any CMakeLists.txt tries to find the compiler.
