tests/avocado/tuxrun_baselines: Fix ppc64 tests for binaries without …

…slirp

The ppc64 tuxrun tests are currently failing if "slirp" has been
disabled in the binary since they are using "-netdev user" now.
We have to skip the test if this network backend is missing.

Fixes: 6ee3624 ("improve code coverage for ppc64")
