[Buildroot] [PATCH 3/3] refpolicy: add ability to set default state.

SELinux requires a config file in /etc/selinux which controls the state
of SELinux on the system.
This config file has two options set in it:
SELINUX which set's the state of selinux on boot.
SELINUXTYPE which should equal the name of the policy. In this case, the
default name is targeted.
This patch adds:
- A choice menu on Config.in that allows the user to select a default
SELinux state.
- A basic config file that will be installed to
target/etc/selinux and will set SELINUX= to the selected state.
