luci-mod-admin-full: use nf_conntrack_count for counting connections (#1114)

Browse source 
As suggested by PR #1114, use `/proc/sys/net/netfilter/nf_conntrack_count`
instead of counting the lines in `/proc/net/nf_conntrack` but use a slightly
more efficient approach which avoids spawning an extra `cat` command.
