Gianluca Zuccarelli e165db63ea metrics: add additional buckets
The change between the 32s bucket and the 64s bucket is too drastic
for measuring the duration of depsolve jobs. At present, 90% of the
depsolve jobs have a duration inbetween 32s and 64s, making the 32s
bucket too sensitive and the 64s bucket not sensitive enough.
