evas/autotools - fix build when no dependencies for examples are found.

Some examples need ecore, ecore-evas and edje to demonstrate its
functionality. If --enable-build-examples is used, these dependencies are
required. This commit disables the examples build if they are not found
in the system.

TODO: improve efl_examples.m4 and use it in evas build too - I'll work on
that soon.
