[Buildroot] [PATCH 1/1] linux/linux.mk: add automatic selinux config selection

[aduskett at gmail.com <aduskett@gmail.com>]

From: Adam Duskett <Aduskett@gmail.com>

Enabling SELinux support in the kernel requires several options, many of which
are in different areas. These options are as follows:

  - CONFIG_AUDIT
  - CONFIG_DEFAULT_SECURITY_SELINUX
  - CONFIG_INET
  - CONFIG_NET
  - CONFIG_SECURITY
  - CONFIG_SECURITY_NETWORK
  - CONFIG_SECURITY_SELINUX

As such, if a user selects the libselinux package, it is much easier to select
these packages for them, much like we already do with other packages
such as systemd or iptables.
