Re: [PATCH 09/12] test libs: rename "diff-lib" to "lib-diff"

Rename the "diff-lib" to "lib-diff". With this rename and preceding
commits there is no remaining t/*lib* which doesn't follow the
convention of being called t/lib-*.

Seeing nothing (other than the OID length abstraction that prepares

this change and no in-flight topics would, either.

Needs a sign-off, though.
