BUG/MINOR: proxy: don't dump servers of internal proxies

Patch 211c967 ("MINOR: httpclient: add the server to the proxy") broke
the reg-tests that do a "show servers state".

Indeed the servers of the proxies flagged with PR_CAP_INT are dumped in
the output of this CLI command.

This patch fixes the issue par ignoring the PR_CA_INT proxies in the
dump.
