Correctly exit from extract_run() and update_run() if files needed are
missing from ${WORKDIR}/files/.

This bug was caused by the astonishing interaction of "return" and
pipelines; in the following code, the "return" does not exit the
function, but instead exits the subshell which was spawned for the last
element of the pipeline; consequently, the output produced is "foo".

foo() {
	echo bar | while read baz; do
		if [ ${baz} = "bar" ]; then
			return 1
		fi
	done

	echo foo
}
