selftests/net: Fix ./ns-XXXXXX not cleanup

```
readonly STATS="$(mktemp -p /tmp ns-XXXXXX)"
readonly BASE=`basename $STATS`
```
It could be a mistake to write to $BASE rather than $STATS, where $STATS
is used to save the NSTAT_HISTORY and it will be cleaned up before exit.

Although since we've been creating the wrong file this whole time and
everything worked, it's fine to remove these 2 lines completely
