Temporarily (?) disable ASLR in the 32-bit kernels

Browse source 
ASLR seems to cause hibernate-related regressions on at least one test
system: https://linux-hardware.org/index.php?probe=e6a06c64c7

When the system tries to resume, it automatically reboots after the
hibernation image has been loaded into memory.

git bisect pointed to the following commit as the first "bad" one:

      x86/KASLR, x86/power: Remove x86 hibernation restrictions

Before this commit, KASLR was disabled (unless enabled explicitly) if
the system supported hibernation.

Let us just disable KASLR for now in the 32-bit kernels - not a big deal
for home & office use, I suppose.
