Currently, if environment variables are set for CCACHE_DIR or SCCACHE_DIR then this action will ignore them and hardcode its own.
This is a problem if CCACHE_DIR is set for example in a docker file environment which is very hard to eliminate
Fixes #96
I think this is a better solution than #165 as that one still suffers from an invalid operation if either of the environment variables are set.
