java: add mraa to the java swig link line so mraa symbols can be found
java: add mraa to the java swig link line so mraa symbols can be found

Previously in MRAA, the libmraa library was statically linked into the
libmraajava library.  This was changed recently in MRAA, causing most
java examples to fail due to missing mraa symbols.  This patch
specifically adds libmraa to the link in addition to libmraajava.

In addition, use *_LIBRARIES in the java specific swig_link_libraries
call rather than *_LDFLAGS.
