[Why] As shown in #10728, in an IPv6-only environment, `kernel` name resolution must be configured through an inetrc file. The temporary hidden node must be configured exactly like the main node (and all nodes in the cluster in fact) to allow communication. Thus we must pass the same inetrc file to that temporary hidden node. This wasn’t the case before this patch. [How] We query the main node’s kernel to see if there is any inetrc file set and we use the same on the temporary hidden node’s command line. While here, extract the handling of the `proto_dist` module from the TLS code. This parameter may be used outside of TLS like this IPv6-only environment. Fixes #10728. (cherry picked from commit 1bcfa47)
