The downloaded zips and their extracted contents lived in separate RUN
layers, so the zips never actually left the image despite a later
rm -rf /tmp/apps layer. unzip/smbclient were also left installed after
only being needed at build time. Merging fetch, extract, cleanup, and
package purge into a single RUN drops the image from 2.31GB to 1.6GB.
