games/eureka: Update to 1.27.2

This release is named 1.27b by upstream (the pkgsrc version is 1.47.2 to
be compatible with the former 1.47.1 that had no upstream name).

Remove libXcursor dependency. Eureka doesn't use libXcursor directly.
It's a FLTK dependency that was missing in the bl3 file (now fixed there).

Upstream changes:
+ fixed a crash bug
