math/pdal: Fix macro check and restore DragonFly support

Add __DragonFly__ definition check in two places to restore the build
on DF.  While here, change __FreeBSD__ value check to existance check
which was the intent I believe (although result is the same).

Approved by:	Restore DF functionality blanket
