qtdeclarative 5.1.0 systemdialogs examples FTBFS

I'm packaging qt declarative 5.1.0 and building the examples, using the submodules tarballs.

The file examples/quick/dialogs/systemdialogs/systemdialogs.pro has an incomplete path (should add systemdialogs to the end), so when the install happens, the binary conflicts with the directory that's supossed to hold it.

I'm attaching the full build log.

The patch is trivial, but please don't hesitate in telling me if you need it non the less.
