fff25a2ad1 exec-randomization: brk away from exec rand area
This is a fix for the NX emulation patch to force the brk area well
outside of the exec randomization area to avoid future allocation or brk
growth collisions. Normally this isn't a problem, except when the text
region has been loaded from a PIE binary and the CS limit can't be put
just above bss.

A test-case that will show failures without this patch can be found here:
