fix: keep go caches on disk instead of tmpfs /tmp

Browse Source 
On the target host /tmp is a tmpfs sized at half of RAM (~970M), so the
go module cache and build cache together filled it and every module
download failed with "no space left on device". Move both caches to
/var/tmp, which lives on the root filesystem, and create both cache
directories up front rather than only the build cache.
