[NEEDS TESTING] Remove "fake" KF5 dependencies from CMakeLists.txt

Removed the following KF5 frameworks: JobWidgets, DBusAddons, TextEditor

Moved the Notifications KF5 framework as required only if INDI is
present.

Builds both with and without INDI (but not in a completely thorough
test) on my setup (ArchLinux)

Jasem: please double check that it builds correctly for you too
with/without INDI.
