vdso: correct remap messages

We should log whom we're remapping, but ~5 lines upper or so
we've unmapped dumpee vdso and vvar. Here we're mremapping runtime
host-provided vdso/vvar blobs to the dumpee position.
Correct the messages to reflect that we've remapped rt-vdso/vvar,
having the same naming as in vdso_do_park().
