perf stat: Add more cache-miss percentage printouts

Print out the cache-miss percentage as well if the cache refs were
collected, for all the generic cache event types.

Before:

   11,103,723,230 dTLB-loads                #  622.471 M/sec                    ( +-  0.30% )
       87,065,337 dTLB-load-misses          #    4.881 M/sec                    ( +-  0.90% )

After:

   11,353,713,242 dTLB-loads                #  626.020 M/sec                    ( +-  0.35% )
      113,393,472 dTLB-load-misses          #    1.00% of all dTLB cache hits   ( +-  0.49% )

Also ASCII color highlight too high percentages, them when it's executed on the console.
