    testsuite: Skip some gcc.dg/plugin tests for default_packed targets
    
    Avoid unweildy structure-layout-specific message-matching
    expressions by exluding targets that lay out structures as
    if they had been specified with __attribute__ ((__packed__)),
    for tests where multiple messages depend on the structure
    layout.
    
    It's arguably a judgement call whether to skip some of these
    tests or add multiple lines of matches depending on the
    layout of structures.
