slirp4netns --version prints multiple lines (version, commit, libslirp,
SLIRP_CONFIG_VERSION_MAX). The old 'awk {print $2}' ran on every line and
also picked the literal word 'version' from line 1, producing a multi-line
blob that leaked into the 'is outdated' notice. Read only the first line and
take field 3 (the actual number), strip the leading v from the GitHub tag so
the comparison is meaningful, and skip the check if the tag fetch fails.
