Remove logiqx tools

[Thomas Klausner <wiz%netbsd.org@localhost>]

Hi!

I propose removing the dat/rom tools by logiqx from pkgsrc, i.e.

emulators/DatLib
emulators/DatUtil
emulators/MAMEDiff
emulators/ROMBuild
emulators/ROMInfo
emulators/ZIPIdent

There is no upstream, the last releases were in 2009, and I don't see
a use case for them any longer (I originally packaged them).

I plan on removing them in a week if there is no disagreement.
