The kernel has very specific rules correlating file type with comment
type, and also SPDX identifiers can't be merged with other comments.

It's good to have SPDX identifiers in all files as the Linux kernel
developers are working to add these identifiers to all files.
Update all files with the correct SPDX license identifier based on the license
text of the project or based on the license in the file itself. The SPDX
identifier is a legally binding shorthand, which can be used instead of the
full boiler plate text.

The reference to this is <https://sourceware.org/glibc/wiki/NameResolver>,
which mentions:
"From the perspective of the application that calls getaddrinfo() it
perhaps doesn't matter that much since EAI_FAIL, EAI_NONAME and
EAI_NODATA are all permanent failure codes and the causes are all
permanent failures in the sense that there is no point in retrying
later."
This should cover more early-boot situations.
While we're at it, we clean up the logic a bit so that we don't have a
retry message on the final non-retrying attempt. We also peer into errno
when receiving EAI_SYSTEM, to report to the user what actually happened.
Also, fix the quoting back tick front tick mess.
