[tools][fuzz] Use tmpfs for faster mutable data storage

Particularly when writing large corpora consisting of many small files,
minfs was acting as a performance bottleneck. This changes undercoat to
transparently map data/ paths to tmp/ paths behind the scenes.

With this change, the e2e test shows a 10x speedup when transferring a
2k element corpus.
