Emscripten: Xfail backtrace ui tests

Browse Source 
It is possible to link libunwind and use the normal backtrace code, but it fails
to symbolize stack traces. I investigated and could get the list of instruction
pointers and symbol names, but I'm not sure how to use the dwarf info to map
from instruction pointer to source location. In any case, fixing this is
probably not a high priority.
