    iconv: Use TIMEOUTFACTOR for iconv test timeout
    
    Currently the timeout for each iconv test is hard coded to 3 seconds.
    On my OpenRISC test platform this is too slow and the test fails with a
    HANG error.
    
    This change uses the available TIMEOUTFACTOR to compute the timeout.
    The default value is still 3.
