mirrorcheck: record duration on file not found errors

On an HTTP 404, FTP 550, or inability to parse the lastsync file, record the
duration of the check even though we couldn't get a time from the mirror.
This allows for these checks to show up as completed but in error, which is
more what.

Previously, inability to parse the date was also recorded as a success, so
change that to be a failure and record an error message with it.
