[PATCH v2 01/15] t/oid-info: allow looking up hash algorithm name

The test_oid function provides a mechanism for looking up hash algorithm information, but it doesn't specify a way to discover the hash algorithm name. Knowing this information is useful if one wants to invoke the test-tool helper for the algorithm in use, such as in our pack generation library.

While it's currently possible to inspect the global variable holding this value, in the future we'll allow specifying an algorithm for storage and an algorithm for display, so it's better to abstract this value away. To assist with this, provide a named entry in the algorithm-specific lookup table that prints the algorithm in use.
