Sysctl nodes are written to, so don't put them in the text section.

Browse source 
Our write protection of the kernel text on i386's doesn't actually
work in many cases:
- use of the 4MB page completely breaks it.
- CR0_WP isn't set until just before init is started, so the kernel
  text is not write protected during kernel initialization.
