Using the conservative version backported to 11u, libraries in `/lib` and `/usr/lib`will still take priority, so the only effect of this change is in allowing the JDK to find libraries on AArch64 systems where libraries are installed in `/lib64` and `/usr/lib64`, where this would currently fail.

The patch did not apply due to differing context and I took this opportunity to also fix the indentation in that section (done as part of the more comprehensive change [JDK-8057109](https://bugs.openjdk.org/browse/JDK-8057109) in OpenJDK 9 and later) rather than breaking the indentation for the new lines.
