Qmake: Fix deploying versioned shared library symlinks

If in a .pro file VERSION is set with less than three version
components, for example "1.0", qmake on Linux still creates the .so with
the following links to it:

- libexample.so
- libexample.so.1
- libexample.so.1.0
- libexample.so.1.0.0

Creator only deployed first three of those.

Pad the version number with zeros to three components in order to find
all of them.
