BUG/MINOR: proxy: fix check_{command,path} leak on deinit()

proxy check_{command,path} members (used for "external-check" feature)
weren't cleaned up in free_proxy(), resulting in small memory leak if
"external-check command" or "external-check path" were used on a regular
or default proxy.

It may be backported to all stable versions.
