t: move reftable/pq_test.c to the unit testing framework

reftable/pq_test.c exercises a priority queue defined by
reftable/pq.{c, h}. Migrate reftable/pq_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.
