speedtest-cli: Fix for bug13805 - error message if run on hour or half hour

- Created a self consistent patch set out of four patches on the speedtest-cli
   github site. Slight changes needed in each to allow them to be successfully applied
   in sequence.
- Additional comments added to top of the various patches.
- Tested out this modified package on my vm testbed and it fixes the bug of
   speedtest-cli giving an error message if run on the hour or on the half hour. I
   tested it out with the original system first and it failed with the error message
   for 7 half hour tests. With this modified version it ran for 9 half hour slots with
   no problems at all. Tested with the command being run via fcrontab.
- None of these patches have ben merged by the speedtest-cli github owner as the last
   commit was July 2021 and the patches were proposed in Feb 2023. There has been no
   resposne to anything on the speedtest-cli github site by the owner.
- I have reviewed all the patches and the content looks fine to me with no concerns
   from a security point of view although it would be good to get feedback from
   alternative eyes.
- Update of rootfile not required.
