Upgrade: do not automatically run euca_conf --setup

The euca_upgrade script, which is used for managing
the upgrade of configuration and database information
during an upgrade, no longer invokes euca_conf --setup,
as its recursive chown/chmod calls could fail in some
cases.

The purpose of euca_conf --setup is to ensure that file
and directory permissions are correct before running
eucalyptus. For packaged installs, the packaging already
takes care of this; for installs from source builds,
euca_conf --setup should be run manually each time a
"make install" is done.

Fixes EUCA-3066
