Tools: bring OSX back to 5.3.1

There is a regression in Qt 5.3.2 for OSX that triggers
segfaults from the serial port when polling the available
ports.

https://codereview.qt-project.org/#/c/95729/

However, 5.3.2 resolved some UI bugs on Linux. Thus, it makes
sense to run separate versions for the time being. Hopefully
this can be dropped with 5.3.3
Packaging: windeployqt needs list of modules to install

Unfortunately windeployqt does not yet seem to search the deployed
plugins for their dependencies recursively. This works on OSX. I
opened a bug report, but this is a workaround until then.

for mode2.
