nft.8: Update meta pkt_type value description

Commit 8a7f6de536408 ("meta: fix pkttype name and add 'other' symbol")
deprecated pkt_type value 'unicast' (for it being misleading) and
introduced 'host' and 'other' but it did not update documentation
accordingly. Fix this by replacing 'unicast' with 'host' in
documentation and adding 'other'.

While being at it, make sure these literal values are recognized as
such: Put them in all lower-case (as required by the parser) and in bold
font (to stand out a bit more).
