[PATCH] base-files: sysupgrade: include uci-defaults script disabling services

[Rafał Miłecki]

From: Rafał Miłecki <rafal at milecki.pl>

Disabled services should be kept disabled after sysupgrade. This can be
easily handled using a proper uci-defaults script.

Extend sysupgrade to check for disabled services, generate uci-defaults
script disabling them and include it in backup.
