Allow "postinst" scripts to perform extra actions after applying all
kind of fixups implemented using uci-defaults.
This is needed e.g. by uhttpd-mod-ubus which after installation in a
running systems needs to:
1. Update uhttpd config using its uci-defaults script
2. Reload uhttpd
While this approach makes sense there is a risk it'll blow up some
corner case postinst usages. There is only 1 way to find out.
