Empty trailing fields get lost when the lines are split and merged again
at colons, resulting in unparsable entries. Only use the split fields for
matching against the other file, but emit the original line unchanged
to fix the issue.
Fixes: de7ca7dafadf ("base-files: merge /etc/passwd et al at sysupgrade config restore")
