BUG/MINOR: proxy: missing free in free_proxy for redirect rules

cookie_str from struct redirect, which may be allocated through
http_parse_redirect_rule() function is not properly freed on proxy
cleanup within free_proxy().

This could be backported to all stable versions.

[for 2.2, free_proxy() did not exist so the fix needs to be performed
directly in deinit() function from haproxy.c]
