Added jtreg-use at openjdk.java.net

I think that you are right. Here is the documentation:

"@requires <expression>

    Express a dependence on characteristics of the system being tested.
    Some harnesses allow tests to be selected according to the
    characteristics of the system being tested. The expression may be
    composed of the following elements:"

"os.arch The operating system architecture, as given by the 
corresponding system property."

So user could expect to have "os.arch" of tested VM.

If filed jtreg issues for this:

 1. CODETOOLS-7901695
    <https://bugs.openjdk.java.net/browse/CODETOOLS-7901695>jtreg uses
    value 'os.arch' property of JDK which executed JDK and not of tested JDK

Following fix could be used as a temporary workaround while jtreg fix is 
not ready.  Does it make a sense? I this case it is needed to change 
linux-arm64 back to linux-aarch64 to minimize changes.
