Remove transitive library dependencies; they are especially
dangerous when one ends up linking against WTF, JSC and then WTF
again, since some symbols will not be defined.

Passing --no-copy-dt-needed-entries and --as-needed to the linker
(which some recent Linux distros do by default) makes the issue
even more evident.

* CMakeLists.txt: Set CMAKE_LINK_INTERFACE_LIBRARIES to an empty
list to prevent implicit transitive library dependencies from
being created by default.

Source/WebCore:

No new tests, this is a buildsystem change.

from it.
* PlatformEfl.cmake: Explicitly link against libjpeg and libpng.

as the other libraries have the needed symbols. Explicitly link
against fontconfig.
