Draft: applets/digital-clock: migrate config from 5.25
If the user changed font settings in 5.25, these settings are ignored when upgrading to 5.26, because 5.26 introduced a new config entry autoFontAndSize, which defaults to true (auto).
This patch adds a kconf_update executable, which sets autoFontAndSize=false when any of fontFamily, boldText, italicText config entries are present.
