Qt 5.6 builds with relative RPATH by default on Linux.
Since this additionally leads to very short RPATHs,
we cannot change the relative structure within the

in lib/qtcreator/).
Instead we now deploy qt into a self-contained lib/Qt/
folder, keeping the original structure, on Linux.

Mostly 7zips the directory, all files must already be in place.
On Linux the script also fixes the Qt related RPATHs.

Changes the RPATH fixing to only change the Qt RPATH,
instead of overwriting the complete RPATH to something custom.
