Set up the /usr/tests hierarchy.

Populate /usr/tests with the only test programs that currently live
in the tree (those in lib/libcrypt/tests/) and add all the build
machinery to accompany this change.

In particular:

- Add a WITHOUT_TESTS variable that users can define to request that
  no tests be put in /usr/tests.
- Add a top-level Kyuafile for /usr/tests and a way to create similar
  Kyuafiles in top-level subdirectories.
- Add a BSD.tests.dist file to define the directory layout of
  /usr/tests.
