Subject: [PATCH] [CI] Remove ccache from Linux CI Container

This patch removes ccache from the Linux CI container. It is no longer
needed after migrating the monolithic-linux.sh script. The other two
upstream users of this container, namely the post commit static analyzer
and the llvm tests workflow both already use sccache.
