Subject: [PATCH net 3/3] selftests: tc: add ConnTrack procfs kconfig

When looking at the TC selftest reports, I noticed one test was failing
because /proc/net/nf_conntrack was not available.

  not ok 373 3992 - Add ct action triggering DNAT tuple conflict
  	Could not match regex pattern. Verify command output:
  cat: /proc/net/nf_conntrack: No such file or directory

It is only available if NF_CONNTRACK_PROCFS kconfig is set. So the issue
can be fixed simply by adding it to the list of required kconfig.

Fixes: e46905641316 ("tc-testing: add test for ct DNAT tuple collision")
