netfilter: complete the deprecation of CONFIG_NF_CT_ACCT 

CONFIG_NF_CT_ACCT has been deprecated for awhile and
was originally scheduled for removal by 2.6.29.

Removing support for this config option also stops
this deprecation warning message in the kernel log.

[   61.669627] nf_conntrack version 0.5.0 (16384 buckets, 65536 max)
[   61.669850] CONFIG_NF_CT_ACCT is deprecated and will be removed soon. Please use
[   61.669852] nf_conntrack.acct=1 kernel parameter, acct=1 nf_conntrack module option or
[   61.669853] sysctl net.netfilter.nf_conntrack_acct=1 to enable it.

Currently used only to set a default value for a feature that is also

help
If this option is enabled, the connection tracking code will
keep per-flow packet and byte counters.
Those counters can be used for flow-based accounting or the
`connbytes' match.
Please note that currently this option only sets a default state.
You may change it at boot time with nf_conntrack.acct=0/1 kernel
parameter or by loading the nf_conntrack module with acct=0/1.
You may also disable/enable it on a running system with:
sysctl net.netfilter.nf_conntrack_acct=0/1
This option will be removed in 2.6.29.
If unsure, say `N'.

This option adds a `connbytes' match, which allows you to match the
