RFR: 8258911: ProblemList serviceability/attach/RemovingUnixDomainSocketTest.java on Linux-X64

[Daniel D.Daugherty]

This is a trivial fix to ProblemList serviceability/attach/RemovingUnixDomainSocketTest.java
on Linux-X64.

The test has been failing fairly frequently in the JDK17 CI when it is run with the
"-XX:NativeMemoryTracking=detail" option. We currently only specify that configuration
on linux-x64 so I'm going to ProblemList the test only on Linux-X64
