module: Move modprobe_path and modules_disabled ctl_tables into the module subsys

Move module sysctl (modprobe_path and modules_disabled) out of sysctl.c
and into the modules subsystem. Make modules_disabled static as it no
longer needs to be exported. Remove module.h from the includes in sysctl
as it no longer uses any module exported variables.

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.
