CI: test build dependent packages

By using OPKGs `whatdepends` all packages dependent on a library are
printed. Use that feature to obtain packages which a version change may
break and build them as well.

Change "default" packages to contain a lib on which other packages
depend, instead of compiling `tmux` compile `attendedsysupgrade-common`
on which other packages depend.

Ignore any LuCI packages which only contains translations.
