ccache: Only pass --ccache-dir when --ccache is used

We are not hiding the arguments from Bazel (yet?),
so changing the --ccache-dir would ccache bust.

Instead we pass --ccache-dir when --cache is not set only
in ebuild_debug, to let people toggle ccache on the
ebuild_debug script.

TEST=flipping --//bazel/portage:ccache doest not rebuild
