Eric Paris a5ecbcb8c1 security: allow Kconfig to set default mmap_min_addr protection ...

Since it was decided that low memory protection from userspace couldn't
be turned on by default add a Kconfig option to allow users/distros to
set a default at compile time.  This value is still tunable after boot
in /proc/sys/vm/mmap_min_addr
