Patch for the Portfile to Bro

[tanawts@…]

Attached is the requested patch to update Bro to the new version: 2.1

[ryandesign (Ryan Carsten Schmidt)]

The distfile for this version doesn't appear to be available from the FTP site so I removed that from the master_sites.

The universal variant doesn't work at all. Initially configuration fails with the message "# Invalid option '--disable-dependency-tracking'. Try ./configure --help to see available options." but removing that argument from configure.universal_args only leads to a build error "error: "Unusual pointer size. Please report to bro@bro-ids.org."" so I disabled the universal variant.

cmake and swig-python are probably build dependencies not library dependencies.

It links with libcurl so I added a library dependency on curl.

I committed the changes in r108832. I changed the whitespace of the changed lines to conform to our preferred style of using spaces instead of tabs. I changed the remaining lines in r108833 and added the standard modeline.
