conda-forge CI: Switch from libccd to libccd-double

[traversaro]

🦟 Bug fix

Fixes #3313

Summary

In conda-forge, the libccd package contains the (deprecated and not updated) single precision build of libccd, while libccd-double containes the double precision build of libccd.

See conda-forge/libccd-feedstock#5 and conda-forge/gazebo-feedstock#137 .

Pulling libccd was forcing us to use a quite old boost, that in the end created problems.

The other failures are unrelated, but the macos-latest@Releaase@conda job now is successful, so the PR is ready for merge.
