t/oid-info: add empty tree and empty blob values

bk2204 · gitster · commit 1bcef5120409 · 2019-10-06T11:45:30.000+09:00
The testsuite will eventually learn how to run using an algorithm other
than SHA-1. In preparation for this, teach the test_oid family of
functions how to look up the empty blob and empty tree values so they
can be used.
