dircache: increase cache size & lifetime
Looking at the dircache debug output, we see that a "git status" workload has a very bad cache hit rate because the entries expire or get evicted before they can be reused. Increase both cache size and lifetime for a 4x speedup: Before: 75s After: 17s https://github.com/rfjakob/gocryptfs/issues/410
