Update MD5Deep

**Updated MD5Deep.**

The source code packages have been moved from Sourceforge to Github, which is reflected here. The way of building of the source code has also changed, which should be executed successfully here.

*SHA1SUM updated as well*.
Oh no, that's fine - I just mean that, if it's running bootstrap, it will require dependencies on autoconf and/or automake.

```rb
depends_on 'autoconf' => :build
depends_on 'automake' => :build
```

Possibly another tool or two depending on what the script calls. Can you test locally to see what it needs? Thanks!
