CI: do not let ccache break the build

The pipeline aborted with "ccache: command not found" at ccache --show-stats.
ccache only makes the build faster, so nothing may depend on it being there:
the compiler symlinks and the cmake launcher options are only set up when it is
actually installed, and printing the statistics can no longer fail the job.

The collocatordb build passed CMAKE_C_COMPILER_LAUNCHER, but collocatordb is
C++, so ccache was never used for it. It sets both launchers now.

Also drops the two `env` calls, which printed all CI variables, including
DOCKER_HUB_PASSWORD and the other secrets, into the job logs.
