uec-query-builds python trace on bad usage or no-builds

Binary package hint: cloud-utils

In 2 cases of uec-query-builds usage, the user gets a python trace. Possibly more annoyingly, they get a apport crash dialog as a result:

$ uec-query-builds is-update-available --build-name server --suite lucid
Traceback (most recent call last):
  File "/usr/bin/uec-query-builds", line 217, in <module>
    main()
  File "/usr/bin/uec-query-builds", line 191, in main
    ( "stream", "base_url", "build_name", "suite", "serial" ))
  File "/usr/bin/uec-query-builds", line 75, in checkopts
    raise Exception("must provide argument for %s" % f)
Exception: must provide argument for serial
