[3/3] qemu-iotests: fix 017 018 for vmdk

017 and 018 use /bin/mv to move base img from t.IMGFMG to t.IMGFMT.base
after filling data, this is not enough for vmdk, when t.IMGFMT is only a
description text file who points to t-{flat,s001,f001,...}.IMGFMT as
data extent, so testing such subformats alway fails on them.

This patch use the trick of temprorily changing TEST_IMG to avoid using
/bin/mv.

s/temprorily/temporarily/


Other than that, I ran the tests locally here and verified vmdk, qcow,
qcow2, and qed pass both 17 and 18, so the patch itself looks good to
me.
