[OE-core] Request for pyro: rootfs-postcommands.bbclass: Prevent linking testdata to itself

[Mike Looijmans]

I noticed this patch made it to master. Could it be applied to "pyro" branch 
please? It's really causing headaches there and there's no "bbclassappend" to 
workaround the issue.

     rootfs-postcommands.bbclass: Prevent linking testdata to itself

     testdata and testdata_link may point to the same file, in particular
     when IMAGE_LINK_NAME and IMAGE_NAME are equal.

     Check if this is the case before creating a symlink that points to
     itself and makes the next build fail.
