object::tweaking: Use the proper kernel configuration

Browse Source 
Currently the module was using incorrect kernel parameters on RedHat
platforms:

 * net.ipv4.netfilter.ip_conntrack_max
 * net.ipv4.netfilter.ip_conntrack_tcp_timeout_time_wait
 * net.ipv4.netfilter.ip_conntrack_tcp_timeout_close_wait

Those parameters has been renamed to match the proper nf_conntrack
parameters[1]
