JFR: Clean up jdk.jfr.internal.RepositoryChunk

[Jaroslav Bachorík]

Hi Erik,

The change looks good.
Only one nit you can feel free to ignore - perhaps `Utils.format()`
could be renamed to `Utild.formatDateTime()` to better signal the
purpose (http://cr.openjdk.java.net/~egahlin/8244463/src/jdk.jfr/share/classes/jdk/jfr/internal/Utils.java.sdiff.html
L185)?

Cheers,

-JB-
