Upstream changes to the build system required adjusting many packages'
dependencies. On the Nixpkgs side, we no longer propagate the dependency
on cmake (to reduce closure size), so downstream dependencies had to be
adjusted for most packages that depend on kdelibs.
This also removes qca2_ossl, because it's now bundled with the main QCA
package and we can now drop all those patches and build system fixes,
because they have switched from autotools to cmake.
Tested against a few builds like PSI and Tomahawk.
