Leigh Brown e27fc7d15e tools/xentop: Fix cpu% sort order ...

In compare_cpu_pct(), there is a double -> unsigned long long converion when
calling compare().  In C, this discards the fractional part, resulting in an
out-of order sorting such as:

        NAME  STATE   CPU(sec) CPU(%)
       xendd --b---       4020    5.7
    icecream --b---       2600    3.8
    Domain-0 -----r       1060    1.5
        neon --b---        827    1.1
      cheese --b---        225    0.7
       pizza --b---        359    0.5
     cassini --b---        490    0.4
     fusilli --b---        159    0.2
         bob --b---        502    0.2
     blender --b---        121    0.2
       bread --b---         69    0.1
    chickpea --b---         67    0.1
      lentil --b---         67    0.1

Introduce compare_dbl() function and update compare_cpu_pct() to call it.
