tests: merge build of tests within main build

Instead of a separate CMakeLists.txt for the tests, make them built
together with the rest of the main project. This behaviour is off
by default, and can be enabled using ENABLE_TESTING.

Furthermore, the testing facilities of cmake are now used, so ctest
(invoked by `make test`) knows about the sqlb-unittests. Thus, adapt
the Travis build steps, building the main sources and executing the
tests twice, one for sqlite and one for sqlcipher.
