[PATCH v3 03/11] t-reftable-record: add comparison tests for ref records

[Chandra Pratap <chandrapratap3519@gmail.com>]

In the current testing setup for ref records, the comparison
functions for ref records, reftable_ref_record_cmp_void() and
reftable_ref_record_equal() are left untested.

Add tests for the same by using the wrapper functions
reftable_record_cmp() and reftable_record_equal() for
reftable_ref_record_cmp_void() and reftable_ref_record_equal()
respectively.
