LocationListLookup test case failing on lldb-arm-ubuntu

Skip on linux+arm for now until I can try to repo the setup of the
lldb-arm-ubuntu bot.  The name of the binary in argv[0] was not
able to be retrieved here; if the compiler's codegen had it stored
in a caller saved register, because it's not needed at this point,
it may not be retreivable.
