The /lib/apk/packages/<pkg>.list file is read by the default_postinst
and default_prerm helpers to find init scripts and uci-defaults of a
package. A layer 1 package keeps its installed record on the uvol
.meta volume and ships volume payloads, not root filesystem files, so
the list would sit on the overlay away from the record that describes
it. Do not generate it when APK_INFO_ selects layer:1; the helpers
treat a missing list as empty.
