Fix ImportError in lldb-mi tests on Linux

[ki.stfu]

Summary

This patch fixes the following error:

 File "/home/llvmbb/llvm-build-dir/lldb-x86_64-clang-ubuntu-14.04/llvm/tools/lldb/test/tools/lldb-mi/signal/TestMiSignal.py", line 5, in <module>
    import lldbmi_testcase
ImportError: No module named lldbmi_testcase

[ki.stfu]

Resolve path to lldbmi_testcase.py

In this patch I use:

sys.path.append(os.path.abspath(os.path.join(os.path.dirname(__file__), '..')))

instead of

sys.path.append(os.path.join(os.path.dirname(os.path.realpath(__file__)), '..'))

make check-lldb is not showing any lldbmi failure after this change. So ok for me. But a person more familiar with python needs to have a look.
