devel/creduce: revive port
Since creduce seems to be maintained after all and has recently had a release
which now works with newer llvm, revive the port.
Fix pkg-plist. @dirrm was run before PORTDATA was added. This was not caught
by pkgng but is caught by pkg_ tools.

Add creduce:
C-Reduce is a tool which takes a large C or C++ program that has a property of
interest (such as triggering a compiler bug) and automatically produces a much
smaller C/C++ program that has the same property. It is intended for use by
people who discover and report bugs in compilers and other tools that process
C/C++ code.
