perf stat: Print cache misses as percentage

Before:

       113,393,041 cache-references         #     83.636 M/sec
         7,052,454 cache-misses             #      5.202 M/sec

After:

       112,589,441 cache-references         #     87.925 M/sec
         6,556,354 cache-misses             #      5.823 %

misses/hits percentages are more expressive than absolute numbers
or rates.

(Also prettify the CPUs printout line to not have a trailing whitespace.)
