RFR: JDK-8320383: refresh libraries cache on AIX in VMError::report [v2]

[Matthias Baesken]

> VMError::report outputs information about loaded shared libraries; but this info could be outdated on AIX because the libraries cache is currently not refreshed before printing.
> This is similar to [JDK-8318587](https://bugs.openjdk.org/browse/JDK-8318587) .
> The refresh in VMError::report could be omitted in some situations where the refresh call is considered problematic.
