From: Stephen Smalley <sds@epoch.ncsc.mil>
This patch removes a hardcoded policy assumption from the get_user_sids logic
in the SELinux module that was preventing it from returning contexts that had
the same type as the caller even if the policy allowed such a transition. The
assumption is not valid for all policies, and can be handled via policy
configuration and userspace rather than hardcoding it in the module logic.
