Disable ccache during kernel module builds
Our module builds always have a 0% ccache hit rate, because the compiler
commands always include the randomized tmpdir. Thus, I'm setting
CCACHE_DISABLE=1 so ccache never saves these one-use objects.
(Besides, we already have our own caching in place for this stuff...)
