dependencies.sh: XBMC needs java & swig on the host

In general, the code-generator is build in two phases. In the first
phase SWIG is used to parse C++ header files that define the API. SWIG
outputs an XML file that contains a complete description of the
structure of the API. In the second phase, the XML file is ingested by a
Groovy (Java) program that then creates C++ code that forms the bridge to the
scripting language (Python).
