[Buildroot] [git commit] linux: add automatic selinux config selection

[Thomas Petazzoni]

commit: https://git.buildroot.net/buildroot/commit/?id=326777c82fb15d8ed9b99a14b9484973d60d8785
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/master

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 options for them, much like we already do with other
packages such as systemd or iptables.
