    testutils: remove internal ABI comment
    
    Some testutils external symbols are marked semi-internals, other
    internals. It is not obvious what guarantees these symbols provide.
    However, tests are now installable, and require the ABI stability
    that glib provides for the rest of the symbols.
    
    In my case, I would like to introduce g_assert* compat code for older
    glib versions, and be able to use the so-called "internal" ABI.
    
    I propose this change to the headers comments to explain the stability
    guarantees. Removing the "internal" = you must not use this, in favor
    of semi-internal = this is not documented.
