tst_QLocale: actually check formattedDataSize() with qint64

Browse Source 
... not just int, and not just non-negative values.

Reveals a problem with bytes == numeric_limit<qint64>::min(), says
ubsan (example; all min64 fail):

    global/qnumeric.h:479:26: runtime error: negation of -9223372036854775808 cannot be represented in type 'long long int'; cast to an unsigned type to negate this value to itself
    text/qlocale.cpp:5062:82: runtime error: signed integer overflow: -2147483648 * 3 cannot be represented in type 'int'
    text/qlocale.cpp:5062:26: runtime error: division by zero
    FAIL!  : tst_QLocale::formattedDataSize(English-Decimal-min) Compared values are not the same
       Actual   (QLocale(language).formattedDataSize(bytes, decimalPlaces, units)): "-inf bytes"
       Expected ("output")                                                        : "-9.22 EB"

So exclude that from testing, for now.
