Subject: lib/oid_registry.c: remove unused sprint_OID
Date: Thu, 1 May 2025 02:05:02 +0100

sprint_OID() was added as part of 2012's commit 4f73175d0375 ("X.509: Add
utility functions to render OIDs as strings") but it hasn't been used. 
Remove it.

Note that there's also 'sprint_oid' (lower case) which is used in a lot of
places; that's left as is except for fixing its case in a comment.
