We now remember the path of each cached file, so when someone truncates that path, we can truncate all open instances of it in cache. Important when someone pipes to stomp a file / opens with O_TRUNC (which FUSE disaggregates into an open() and then a truncate() call). Gets rid of the need for FUSE_CAP_ATOMIC_O_TRUNC, which never worked on macOS anyway. Fixes #40.
