Cygwin: disable high-entropy VA for cygcheck and strace 

It's not a good idea to enable high-entropy VA for tools loading the
Cygwin DLL dynamically.  The addresses used by HEVA tend to collide with
fixed address areas managed by Cygwin.

Fixes: 60675f1a7e ("Cygwin: decouple shared mem regions from Cygwin DLL")
