Add a dummy Store::buildPaths() method

This default implementation of buildPaths() does nothing if all
requested paths are already valid, and throws an "unsupported
operation" error otherwise. This fixes a regression introduced by
c30330df6f67c81986dfb124631bc756c8e58c0d in binary cache and legacy
SSH stores.
