hack/update-swagger-spec.sh(cleanup): fix signal handler to really cleanup etcd and minor improvements.

Browse Source 
Prior this change, etcd wasn't cleaned up on my machine that lead to
orphaned etcd process after the update-swagger-spec.sh failed.

This change also adds additional improvements:
- don't kill/wait/rm when argument is empty.
- use kube::util::trap_add.
