[PATCH 2/3] selftests/net: Fix ./ns-XXXXXX not cleanup

[Li Zhijian]

```
readonly STATS="$(mktemp -p /tmp ns-XXXXXX)"
readonly BASE=`basename $STATS`
```
It would 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.
