Use jstemmer/go-junit-report/v2 to correctly parse go test output.

Problem

jstemmer/go-junit-report(v1) may not parse output correctly. For example, if I try to parse the following output, I want all the output to be put in the failure message, but only the first line is actually put in. The following output is generated by github.com/stretchr/testify/assert.

=== RUN   TestGetTestListFromPkgs
    /Users/shibayu36/development/src/github.com/Songmu/gotesplit/gotesplit_test.go:149:

Solution by PR

jstemmer/go-junit-report/v2 can correctly parse output. It outputs the following when it parses the same content above.

Copied and pasted from https://github.com/jstemmer/go-junit-report/blob/v2.0.0/internal/gojunitreport/go-junit-report.go#L73-L93.

If the master branch of go-junit-report is released, https://github.com/jstemmer/go-junit-report/blob/master/junit/junit.go#L41 can be used, but it has not been but it has not been released for a while. ref: jstemmer/go-junit-report#164
