RFR: 8371697: test/jdk/java/nio/file/FileStore/Basic.java fails after 8360887 on linux [v4]

> Hi all,
> 
> The new method testFileAttributes in test/jdk/java/nio/file/FileStore/Basic.java added by [JDK-8360887](https://bugs.openjdk.org/browse/JDK-8360887)/[JDK-8361183](https://bugs.openjdk.org/browse/JDK-8361183) fails on some linux machines. A FileSystemProvider may support many views but some of these attributes in these views may not supported on all FileStores. So I think the new added check `haveView == supported` is too strict on non-AIX systems. This PR make this check only on AIX.

SendaoYan has updated the pull request incrementally with one additional commit since the last revision:

  Replace assertNotNull for "Files.getFileAttributeView(file, viewClass)" when supported is true
