Subject: [PATCH] tests: gnrc_sixlowpan: replace default netif with dummy
Use a minimalistic dummy instead of the default interface for testing
the `gnrc_sixlowpan` module
Currently the default interface is used which leads to problems with
this test, since random traffic on the medium might lead to failed
results.
