Fails to declare dependency on either gksu or kdesudo

[javabrett]

In a very stripped/bare-bones install (e.g. starting from a Docker image), neither gksu nor kdesudo may be installed, and mintdrivers relies on one or the other, in the launch script:

if os.path.exists("/usr/bin/gksu"):
    launcher = "gksu  --message \"<b>%s</b>\"" % sentence
elif os.path.exists("/usr/bin/kdesudo"):
    launcher = "kdesudo -i %s -d --comment \"<b>%s</b>\"" % (icon, sentence)

There's no final else, so you end-up with an error:

NameError: name 'launcher' is not defined
