Subject: evaluate: reject: fix dependency generation from nft -f
When nft -f is used, ctx->cmd points to the table object, which
contains the corresponding chain, set and rule lists. The reject
statement evaluator relies on ctx->cmd->rule to add the payload
dependencies, which is doesn't point to the rule in that case.
This patch adds the rule context to the eval_ctx structure to update
the rule list of statements when generating dependencies, as the reject
statement needs.
