archive-tar: report wrong pax extended header length
Extended header entries contain a length value that is a bit tricky to
calculate because it includes its own length (number of decimal digits)
as well. We get it wrong in corner cases. Add a check, report wrong
results as a warning and add a test for exercising it.
