Move the randomize_va_space variable together with all its sysctl table
elements into memory.c. Register it to the "kernel" directory by
adding it to the subsys initialization calls
This is part of a greater effort to move ctl tables into their
respective subsystems which will reduce the merge conflicts in
kernel/sysctl.c.
