Make Bazel build dot

This change has several parts, it:

* Adds a "make" repository rule, which runs ./configure && make on a
  repository.
* Modifies the tar.gz decompressor to restore timestamps. This was
  an issue with dot, as make examines the timestamp to determine if
  files need to be rebuilt. Because Bazel was not preserving the
  archive's timestamp, it was rebuilding things that it did not need to
  (and, I think, exposed some bugs in dot's Makefile).
* Actually add dot as an external repository. I made the dot-graph
  target manual, so it won't be downloaded/built by the default //...
  target.
* Remove dot scrubbing from the Bazel export process.
* Added some names to download_and_extract params, because it's really
  annoying to only be able to reference them positionally.
