fix paths to test binaries

[matlo607]

I could not execute the unit tests on Linux after a build with the package manager conan.
I got various errors as below :

Could not find executable /home/vagrant/.conan/data/qpid-proton/0.17.0/murex/testing/build/0a97a1801350fba2ff4f9c864097f04752c8d5c5/build-dir/proton-c/bindings/cpp/codec_test
...
The following tests passed:
        python-test
        cpp-example-container

11% tests passed, 17 tests failed out of 19

Total Test time (real) =  38.84 sec

The following tests FAILED:

@matlo607 Sorry this change looks good, but it makes the regular CI build fail because now it can't find the same binaries!

So Look at the Travis output above and try to figure out a change that will work in all cases.

@astitcher
Please could you give me some hints to fix the build on Windows ?
I don't have a clue and a Windows machine too.

@matlo607 I think this may be fixed with change b172262. If you have a chance can you check and close this PR if it is fixed.
