Exit properly from exit handler

This fixes a problem where two SIGINT (Ctrl+C) signals were needed to
terminate an ongoing compilation. (The first SIGINT terminated the
compiler which exited with non-zero status, which ccache then went on
interpreting as an ordinary failed compilation, leading to rerunning the
compiler via failed().)
