Correct patch of configure scripts for DragonFly/FreeBSD.
That place was changed prior to my update of ruby193-base pacakge and
I'm not sure it was correct or not.

And suffix of libruby shared library has something historical part of
pkgsrc.  I don't care so much to changing the name, but also don't
think it is so important thing to bump revisions.

Noted by pkg/47831 from David Shao.
treat DragonFly same as newer FreeBSD.
