Patch for robots 2.0-3

[Andre Bleau <bleau@igb.umontreal.ca>]

I've noticed that robots 2.0-3 fails to update its high score files with 
cygwin 1.5.x. Debugging shows that the bug is related to lseek. Searching 
the archives, I found this message from cgf:

So, here's a patch to robots.h to do just that:
$ diff -u robots.h robots.h.new
--- robots.h    2003-07-18 11:23:57.001000000 -0400
+++ robots.h.new        2004-05-04 13:23:50.407687000 -0400

Now I'm back to the top 20 robot killers of all time (on my machine):

$ ./robots
