Couple of APIs used by KernelShark have been marked as deprecated
in the recent version of Qt. Fix all compilation warnings caused
by the usage of these deprecated APIs.

The library that provides the OpenGL plotting instruments, used by
the KernelShark GUI is remove from the "libkshark-devel" installation
component. In fact this library was never a true (functional) part
of "libkshark-devel", since its header files were never installed.

So far "install_libkshark-devel.sh" was an unofficial script that
was used to help installing the "libkshark-devel" component. It was
introduced, because the CMake syntax for doing this is quite hard to
memorize. Here we make this script an integrated part of the build
system. The message output is made consistent with the messages
printed by "install_gui.sh". The usage of the script is explained
in README.
