Update DL_DIR and SSTATE_DIR in local.conf
After moving from kas to the repo tool, DL_DIR and SSTATE_DIR are no longer changed in the 'local.conf' file.
It always creates a DL_DIR and SSTATE_DIR outside the build directory to avoid losing the cache files after deleting them.
Different paths can be passed thru environment variables.
