netfilter: uapi: correct UNTRACKED conntrack state bit number

Browse source

nft_ct exposes this bit to userspace.  This used to be

  #define NF_CT_STATE_UNTRACKED_BIT              (1 << (IP_CT_NUMBER + 1))
  (IP_CT_NUMBER is 5, so this was 0x40)

.. but this got changed to 8 (0x100) when the untracked object got removed.
Replace this with a literal 6 to prevent further incompatible changes
in case IP_CT_NUMBER ever increases.
