[PATCH][SELINUX] Remove hardcoded policy assumption fromget_user_sids logic

[Stephen Smalley]

This patch against 2.6.6-rc1-mm1 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.
