RFR: 8188869: jdk9/10 reject zip/jar files where seconds value of timestamp is out of supported range 0 - 59

[Claes Redestad]

Hi,

please review this bug fix to ensure we don't reject jar
and zip files due to entries having malformed timestamps.

Webrev: http://cr.openjdk.java.net/~redestad/8188869/jdk.00/
Bug: https://bugs.openjdk.java.net/browse/JDK-8188869

I opted to only fall back to the more lenient JDK 8 version when
we need to, which is important to not re-introduce a scalability
bottleneck, see micros and results here:
