    gkeyfile: Avoid an unnecessary strcmp()
    
    As the groups are disambiguated by name via the `groups` hash table,
    there is guaranteed to be at most one `GKeyFileGroup` instance per group
    name, which means they can be compared for equality by `GKeyFileGroup`
    pointer, rather than needing a `strcmp()`.
    
    This speeds up key file parsing in all cases.
