reftable/tree_test.c exercises the functions defined in
reftable/tree.{c, h}. Migrate reftable/tree_test.c to the unit
testing framework. Migration involves refactoring the tests to use
the unit testing framework instead of reftable's test framework and
renaming the tests to align with unit-tests' standards.
