ldns, ldns-tools, drill upstream update

[marius.rieder@…]

Upstream update to ldns version 1.6.1.

The two patches in net/drill/files can be removed.

Thanks for the updates.

• r58033: committed your ldns update
• r58034: committed your ldns-tools update, except:
  • I undid your dependency change from "port:ldns" to "port:-ssl:ldns" because that's not valid dependency syntax and I'm guessing that was a typo
  • I undid your addition of "--mandir=${prefix}/share/man" to the configure.args because this software already knows where manpages should go
  • I undid your addition of "build.type gnu" because that is the default
• r58035: made ldns-tools share the dist_subdir with the ldns port so the distfile doesn't have to be downloaded twice
• r58036: committed your drill update, and made it share the dist_subdir with ldns
