    diagnostics: Fix selftest ICE in certain locales [PR107722]
    
    As reported in the PR, since special_fname_builtin () call has been
    introduced, the diagnostics code compares filename against _("<built-in>")
    rather than "<built-in>", which means that if self tests are performed
    with the string being translated, one self-test fails.
    The following patch fixes that.

            * diagnostic.cc (test_diagnostic_get_location_text): Test
            special_fname_builtin () rather than "<built-in>" and expect
            special_fname_builtin () concatenated with ":" for it.
