Add support for DragonFly BSD x86_64

DragonFly BSD is currently x86_64 only, so don't bother other
architectures at the moment.

The changes are based on the existing support for other BSDs.

One extra change is made to native/Makefile by adding the 'X11INCDIR'
variable, so that it can be easily overrided to be '/usr/local/include'
on DragonFly and FreeBSD.

Tested on DragonFly 6.5 with OpenJDK 17.0.8 and Ant 1.10.13.
