That linking is done in initscripts. Removing this line will fix the 
issue
<https://git.yoctoproject.org/poky/tree/meta/recipes-core/initscripts/initscripts-1.0/volatiles?h=master-next#n32>

But that would affect not only ptest images. It would additionally be 
needed to adjust that recently added commit:
<https://git.yoctoproject.org/poky/commit/meta?h=master-next&id=d5d40479d706cbb382850b9479c5dd9bfb801c99>

So this would be quite invasive. Overall the logic here is just the 
other way around as described in the systemd documentation, where /tmp 
should be volatile and /var/tmp should be covered by physical memory
