Force rebuild of ros-rolling-ompl in CI cache

The cached ros-rolling-ompl was built against an older Boost whose
omplConfig.cmake requires the boost_system component. Boost 1.90 ships
Boost.System as header-only with no boost_system-config.cmake, so
downstream find_package(ompl) fails. Evict it from the build cache so it
is rebuilt against the current Boost.
