Fix updating of file changes if packaged template already exists
When you create a file or app-template and package it using the corresponding macros the packaged template is not updated when the files change.
I remember this being extremely confusing/annoying when I first started playing around with the KDevelop templates ;-).
Regarding the u option the tar manual says:
Append files which are newer than the corresponding copy in the archive.
Which is exactly what we want.
