ci: fix junit test output parsing (#890)

After upgrading to Go 1.20 there was a breaking change in the test
output, in which resuming tests print NAME instead of CONT.

https://go-review.git.corp.google.com/c/go/+/443596

The go-junit-report utility does not properly parse NAME, so this hack
replaces the output to look how it did before. The upstream
go-junit-report should be fixed to properly parse the new gotest output
format.
