[11u] RFR: JDK-8223697 jfr tool can't format duration values greater than 1 minute

[Jie Kang]

Hi,

Please review this backport for [1]. The fix did not apply cleanly due
to line differences from missing backport of [2]. The additions are
the same but at different lines than in jdk/jdk.

This fix is quite small and useful for the jfr tool in jdk 11. The
tier one and jfr tests ran successfully on my machine.
