tests/qapi-schema: Drop redundant flat-union-inline test

flat-union-inline.json covers longhand branch definition with an
invalid type value.  It's redundant: longhand branch definition is
covered by flat-union-inline-invalid-dict.json, and invalid type value
is covered by nested-struct-data.json.  Drop the test.
