security: use mmap_min_addr indepedently of security models
commit e0a94c2a63f2644826069044649669b5e7ca75d3 upstream.
This patch removes the dependency of mmap_min_addr on CONFIG_SECURITY.
It also sets a default mmap_min_addr of 4096.
mmapping of addresses below 4096 will only be possible for processes
with CAP_SYS_RAWIO.
