[libunwind] Always use unwind tables in tests
    
For many targets setting -fno-exceptions will prevent unwinding tables from
being generated for the test programs. As libunwind depends on the tables to
unwind the stack several tests will fail.

This change always adds -funwind-tables so that even when -fno-exceptions
is set unwind tables are generated.
