All kernel scripts will now export KERNELDIR at the end.
This way, they are also free to echo whatever they wish to stdout since stdout is no more used.

Source the download-headers script so that KERNELDIR gets set.

Since everything is put in a single bash script here, we don't even need to source kernel-download script.

local executor needs to fetch KERNELDIR after exec.Command runs.
The only way is to fallback at the old method of echoing KERNELDIR at the end of the script; then we will parse script stdout line by line and the last one will be our KERNELDIR path.

Dropped some . at the end of log strings for local executor, for consistency.
