tests: py: replace "eth0" with "lo" in dup expr tests

This patch follow up on Manuel's commit a8871ba6daa0 ("tests: py: any:
Make tests more generic by using other interfaces"). The ifindex of
"eth0" is not always 1, furthermore, "eth0" maybe not exist on some
systems. So replace it with "lo" will make tests more rubost.

In other test cases, "eth0" is used by iifname or oifname, so there's no
need to convert it to "lo". Even if "eth0" is not exist, test will never
fail.
