oeqa.buildperf: another fix for splitting 'nevr' string
When processing buildstats we determine recipe name, epoch, version and
revision from the per-recipe buildstat directory name. One previous
patch made an assumption that package version starts with a number.
That might not be true because of a packaging mistake or whatever
reason. Thus, if a version starting with a number is not found, fall
back to the "old" method of just taking the second-last dash-delimited
part (the one before revision).
