all: address do_compile proxy issues

Created by: StaticRocket

The compile phase of certain packages depends on a loopback websocket connection. If a proxy is exported for this without a corresponding no_proxy config containing localhost, ::1, and 127.0.0.1, it will result in a connection issue and error out.

If we're exporting most of the proxy variables manually now then lets just use the export_proxy command from bitbake directly were proxies are needed.
