Ian Campbell fd24308e6e pkg/jsonmessage: Wrap test failure messages so control characters align ...

When logging the failure of a case which involves control characters add line
feeds and spacing such that the expected and actual strings are aligned in the
same columns making comparisons easier.

Turns:
	jsonmessage_test.go:156: Expected "\x1b[2K\rstatus      1 B\r", got "\x1b[1K\x1b[K\rstatus      1 B\r"
Into:
	jsonmessage_test.go:156:
		Expected "\x1b[2K\rstatus      1 B\r"
		     got "\x1b[1K\x1b[K\rstatus      1 B\r"
