test: move Lua tests from /static-build/test to /test/app-tap

The tests are TAP compatible and applicable to all Tarantool builds so
there's no need to run them with ctest. We just need to add a couple
skip conditions:
 - The luarocks test shouldn't be run on dynamic builds because luarocks
   modules aren't embedded there.
 - The traceback test should be run only if ENABLE_BACKTRACE was set at
   build time.
