Update obsolete files list for OpenSSL 1.1.1.

This will need a real date once this is merged to head.

One weird thing to note: the 32-bit engines get dumped into /usr/lib32
rather than /usr/lib32/engines, and I bet the 32-bit libcrypto.so i
looking for the .so files in the wrong place. We should probably fix
both of those at some point.
