Some tests use the dummy kernel module. This commit adds a function to
automatically load that module and remove it afterwards.

Some tests use hard coded interface names and iterface indexes.
This commit removes these cases by exchanging "eth0" with "dummy0" and
"lo" (depending on the test) in all ifname tests and by using "lo"
instead of "eth0" in all interface index tests (because we can assume
"lo" ifindex is 1).
