Add local bindep.txt

As it was announced [1] global bindep-fallback.txt was removed and now
projects need to have a local bindep.txt to be able to install binary
dependencies for testing.

In test jobs the script tools/test-setup.sh is called which requires
mysql and postgres servers and clients to be installed.
