tool rename

The tool app name changed from `leveldb` to `leveldbtool` considering
the following reasons:

* `leveldb` looks like an official app, but it's not.
* It is confusing when binary has a name as same as the library, so nimble
  warned about hybrid projects.
* The new sketch of the binary project offered by nimble does not include
  `bin` directory.
