RFR: 8259865: (fs) test/jdk/java/nio/file/attribute/UserDefinedFileAttributeView/Basic.java failing on macOS 10.13

[Alan Bateman]

This is a workaround to a bug in fgetxattr(2) on macOS 10.13.6 with APFS where it doesn't return -1/ERANGE when the buffer is too small.  This bug leads to UserDefinedFileAttributeView/Basic.java failing on macOS 10.13 systems, the test is passing on 10.14 and 10.15. The change just means that FileStore.supportsFileAttributeView will return false when asked if it supports UserDefinedFileAttributeView.class.
