libnftables: Unexport enum nftables_exit_codes

Apart from SUCCESS/FAILURE, these codes were not used by library
functions simply because NOMEM and NONL conditions lead to calling
exit() instead of propagating the error condition back up the call
stack.

Instead, make nft_run_cmd_from_*() return either 0 or -1 on error.
Usually errno will then contain more details about what happened and/or
there are messages in erec.

Calls to exit()/return in main() are adjusted to stay compatible.
