oo-accept-node: Handle non-existence of /sbin/ip

Modify check_node_public_resolution to rescue from Errno::ENOENT when
running /sbin/ip in case the command does not exist.  This change makes
check_node_public_resolution consistent with the find_ext_net_dev test.

This commit fixes bug 1121224.
Fix frontend system_proxy_delete/system_proxy_set

OpenShift::Runtime::FrontendProxyServer#system_proxy_delete and
OpenShift::Runtime::FrontendProxyServer#system_proxy_set: Return values in
a consistent ordering (stdout, stderr, exit status) irrespective of whether
arguments were passed.

Previously, these methods returned the exit status as the first value
instead of the last if no arguments were provided.

Fix the corresponding test cases to expect the correct ordering.

This commit fixes bug 1121238.
