RFR: 8338884: java/nio/file/attribute/BasicFileAttributeView/CreationTime.java#tmp fails on alinux3 [v4]

[SendaoYan]

> Hi all,
> On alinux3(alibaba cloud linux version 3) system, the `/tmp` disk partition is mounted as tmpfs filesystem type, this filesystem type doesn't support create time(birth time).
> 
> Before this PR, this test [check](https://github.com/openjdk/jdk/blob/master/test/jdk/java/nio/file/attribute/BasicFileAttributeView/CreationTime.java#L110) if there is `statx` system call present or not to determise the test environment support birth time or not. I think it's not enough when the tested filesystem type is `tmpfs`. When the tested filesystem type is `tmpfs`, then the tested file doesn't support birth time.
> 
> Test fix only, the change has been verified, no risk.
