[PATCH RFC] base-files: execute package's "postinst" after executing uci-defaults

[Rafał Miłecki]

From: Rafał Miłecki <rafal at milecki.pl>

With this change "postinst" scripts can 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

I noticed that kind of hacky code was added in the commit d25d281fd668
("uhttpd: Reload config after uhttpd-mod-ubus was added") to reload
uhttpd after "opkg install". It abuses uci-defaults script to call
init.d script. It's a wrong idea as uci-defaults should run before
running services during first boot. It doesn't allow further config
adjustments by other uci-defaults as uhttpd gets started early.

This change would allow moving uhttpd-mod-ubus's reload to postinst.

The question is: can this change break anything?
