Peter Müller ef21f3e49d sysctl: improve KASLR effectiveness for mmap
By feeding more random bits into mmap allocation, the
effectiveness of KASLR will be improved, making attacks
trying to bypass address randomisation more difficult.

Changed sysctl values are:

vm.mmap_rnd_bits = 32 (default: 28)
vm.mmap_rnd_compat_bits = 16 (default: 8)
