WIP: zoneminder: new package

FIXME: It doesn't run! Perl modules not found (even though they're
wrapped).

----
ZoneMinder is a video camera security and surveillance solution.

http://www.zoneminder.com/

Implementation notes:
- ZoneMinder needs DBD::mysql, and the currently packaged version
  doesn't build (or tests fail), so I upgraded it to the latest version,
  4.023 (was 4.013).
- Some extra (optional) Perl modules are also added:
  Sys::Mmap, Expect, MIME::Tools, MIME::Lite
