libpreludedb, prelude-lml, prelude-manager: Update

[ryandesign (Ryan Carsten Schmidt)]

libprelude is at the current version 5.2.0 but libpreludedb, prelude-lml and prelude-manager are at much older versions and reference what appears to be an outdated homepage for the project. (​Per Wikipedia, in 2014 "Prelude IDS becomes Prelude SIEM".)

$ port info --name --version --homepage name:prelude

Perhaps the three other ports could be updated to match libprelude. It is probably a good idea to always keep these four ports updated together. A comment could be added into each Portfile to remind of that.

There is one other open ticket about libpreludedb right now that could be addressed in such an update.

Cc'ing maintainer of libprelude in case they would like to take on maintenance of these other ports.

libpreludedb, prelude-lml and prelude-manager updated to 5.2.0 recently. However, after enabling +python38 as a default in libprelude, it doesn't build successfully on the OSX 10.12 or earlier buildbots. (See #64805.) Therefore, libpreludedb. prelude-lml and prelude-manager are unable to build on those configurations. Will attempt to follow up.
