[refpolicy] [PATCH 1/1] Separate domtrans/run interfaces for portage_fetch

[sven.vermeulen@siphos.be (Sven Vermeulen)]

Since the introduction of the portage_fetch_t domain, access to the
domain was governed through the portage_domtrans and portage_run
interfaces. To support calling portage only (but no fetch domain) or
vice versa, the interfaces need to be split up.

In this patch, we introduce the interfaces portage_domtrans_fetch and
portage_run_fetch which will be used later in the domains that need to
call portage/layman/emerge-webrsync/...
