src: add NFTNL_SET_EXPRESSIONS

NFTNL_SET_EXPR defines the stateful expression type that this set stores
in each element. This provides the set definition in terms of stateful
expressions. The expression that is passed via NFNTL_SET_ELEM_EXPR must
equal to this set stateful expression type, otherwise the kernel bails
out.

This patch adds support for the set expression list, which generalizes
NFTNL_SET_EXPR.

This patch also adds nftnl_set_add_expr() to add new expressions to a set
and nftnl_set_elem_expr_foreach() to iterate over the list of expressions.
