Add missing libraries when linking xenia-app on Linux

Currently, each module in Xenia is built as a static library (also
called archive). On Linux, an archive only contains the object files
for that module. So any depedency that module has must be specified by
adding those other modules when linking the program, as the dependencies
are resolved at that time.
