[refpolicy] [PATCH 2/2] Support emerge-webrsync through portage domain

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

The emerge-webrsync application fetches snapshots (archives), extracts them and
then synchronizes the local tree with the snapshot. It uses portage code (and 
libraries) to do so, but is implemented as a wrapper as it also offers the 
possibility of verifying the GPG signature of the snapshot first.

By putting emerge-webrsync in portage' domain, it is handled through the regular
portage_run() and portage_domtrans() methods. It is also necessary to put it in
this domain for unattended/automated calls, such as through cron and puppet.
