BUG/MINOR: http_htx: Initialize HTX error messages for TCP proxies

Since the HTX is the default mode for all proxies, HTTP and TCP, we must
initialize all HTX error messages for all HTX-aware proxies and not only for
HTTP ones. It is required to support HTTP upgrade for TCP proxies.

This patch must be backported to 2.0.
