[PATCH 5/5] perf test: squelch warnings about undefined sizeof

[Ramkumar Ramachandra <artagnon@gmail.com>]

perf test emits the following warnings on the parse events test:

  $ perf test
   5: parse events tests
    Warning: function sizeof not defined
    Warning: function sizeof not defined
    Warning: function sizeof not defined
    Warning: function sizeof not defined
    Warning: function sizeof not defined
    Warning: function sizeof not defined
    Warning: function sizeof not defined
    Warning: function sizeof not defined
    ...

Squelch the warnings by explicitly ignoring the sizeof function.
