Hi!

While working on the “reproducible builds” effort [1], we have noticed
that plasma-framework could not be built reproducibly.

Plasma-fraamework uses a macro in extra-cmake-modules that causes
unreproducible tars.
Cmake tar command does not allow for switches that fix
umask and user/group inconsistancy which cause unreproducible builds. This
patch
takes the tar command used in kdevplatform that has all the required
switches
to
make builds that use this macro reproducible.. Once applied,
plasma-framework can be built reproducibly in our current experimental
framework.
