    gmacros: Fix G_[UN]LIKELY to not mask -Wparentheses
    
    A double paren forces the compiler to assume that the
    statement is right.  That may not be the case.
    
    This is essentially reverting b44fba25fbad89c105795a10a569fe422e4d1c44.
    See https://bugzilla.gnome.org/show_bug.cgi?id=760215.
    
    It's more morth to allow find common mistakes (= instead of ==
    in conditionals) than masking them to make some rarely used
    code work.
