hashcat: 0.49 -> 2.00
hashcat: 0.49 -> 2.00

The current URL is broken, upstream has moved the download from .../files/ to
.../files_legacy/. But after fixing that, starting hashcat results in:

  $ ./result/bin/hashcat
  ERROR: this copy of hashcat is outdated. Get a more recent version.

So just update to latest.

New releases are on github, the license is now MIT and there are build
system changes.
