    scripts/package-metadata.pl: fix overriding conditional dependencies with conditional select
    
    Conditional dependencies use the '(!cond) || dep' syntax, whereas
    conditional select uses 'dep if cond'.
    Add an extra check to suppress emitting a conditional if an equal
    conditional select already exists.
