Mark Fasheh 021404bb6a scoutfs: remove inode ctime index ...

Like the mtime index, this index is unused. Removing it is a near
identical task. Running the same createmany test from our last
patch gives us the following:

 $ createmany -o '/scoutfs/file_%lu' 10000000

 total: 10000000 creates in 598.28 seconds: 16714.59 creates/second

 real    9m58.292s
 user    0m7.420s
 sys     5m44.632s

So after both indices are gone, we go from a 12m56 run time to 9m58s,
saving almost 3 minutes which translates into a total performance
increase of about 23%.
