Subject: [PATCH] lib: add SELinux include and stub functions
Bugzilla: https://bugzilla.redhat.com/show_bug.cgi?id=1780023
Upstream Status: iproute2-next.git commit e246ebc3

lib: add SELinux include and stub functions
ss provides some selinux stub functions, useful when iproute2 is
compiled without selinux support.
Move them to lib/ so we can use them in other iproute2 tools.
