libnftables: Simplify nft_run_cmd_from_buffer footprint
With libnftables documentation being upstream and one confirmed external user (nftlb), time to break the API! First of all, the command buffer passed to nft_run_cmd_from_buffer may (and should) be const. One should consider it a bug if that function ever changed it's content. On the other hand, there is no point in passing the buffer's length as separate argument: NULL bytes are not expected to occur in the input, so it is safe to rely upon strlen(). Also, the actual parsers don't require a buffer length passed to them, either. The only use-case for it is when reallocating the buffer to append a final newline character, there strlen() is perfectly sufficient.
