[*] remove tests directory

Testing has been done using the test repo exclusively for quite some
time now: https://bitbucket.org/phg/lua-la-tex-tests. Also, the
``mktests`` script partially automates testing of the font management.

This changeset is just codifying the facts.
If any of the tests deserves preservation please file an issue for
inclusion into the test repo.
Thanks!
