greatroar e5d597fd22 bloblru: Upgrade to hashicorp/golang-lru/v2 
The new genericized LRU cache no longer needs to have the IDs separately
allocated:

name   old time/op    new time/op    delta
Add-8     494ns ± 2%     388ns ± 2%  -21.46%  (p=0.000 n=10+9)

name   old alloc/op   new alloc/op   delta
Add-8      176B ± 0%      152B ± 0%  -13.64%  (p=0.000 n=10+10)

name   old allocs/op  new allocs/op  delta
Add-8      5.00 ± 0%      3.00 ± 0%  -40.00%  (p=0.000 n=10+10)

greatroar 634a9c162d Check cap instead of len in bloblru 
restic dump uses bloblru.Cache to keep buffers alive, but also reuses
evicted buffers. That means large buffers may be used to store small
blobs, causing the cache to think it's using less memory than it
actually does.
