Avoid double-caching when ccache is installed in PATH On Linux, ccache is typically installed in $PATH as /usr/lib64/ccache/g++ or similar. If we keep it there, all compilations will be cached by both ccache and sccache. While the user could easily disable ccache with CCACHE_DISABLE, it's reasonable to assume many will forget and will have their disk space doubly consumed by both caches. Better to recognize this and disable ccache under sccache. This patch does this by removing the ccache binary paths from $PATH. Fixes #2519
