Update lorax wrapper to use --installpkgs

The lorax wrapper class now understands the --installpkgs argument and
can use it to pass multiple package names to the command.

There is a simple test to make sure the commands includes all specified
options. A bug is fixed where the bug URL would not be correctly
included.
