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

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.
