[PATCH nft 3/3] bison: permit keywords in list_stmt_expressions

[Florian Westphal <fw@strlen.de>]

'ct event set label' and 'ct event set new or label' work, but
'ct event set new, label' did not:

  nft add rule filter input ct event set new,label
  Error: syntax error, unexpected label

This changes the definition to also contain keyword symbol expressions.
