Fix issue where mod_ssl does not pick up the ssl-unclean-shutdown

setting when configured e.g. as a reverse proxy:

* modules/ssl/ssl_private.h: Remove ssl_hook_Translate.

* modules/ssl/ssl_engine_kernel.c (ssl_hook_ReadReq): Merge in
ssl_hook_Translate.  (ssl_hook_Translate): Remove.

* modules/ssl/mod_ssl.c (ssl_register_hooks): Ensure that _ReadReq
hook runs after mod_setenvif.c; don't register translate_name hook.
