selftests: net: lib.sh: Don't defer failed commands

Usually the autodefer helpers in lib.sh are expected to be run in context
where success is the expected outcome. However when using them for feature
detection, failure can legitimately occur. But the failed command still
schedules a cleanup, which will likely fail again.

Instead, only schedule deferred cleanup when the positive command succeeds.

This way of organizing the cleanup has the added benefit that now the
return code from these functions reflects whether the command passed.
