crypto: prefix module autoloading with "crypto-"
commit 5d26a105b5a73e5635eae0629b42fa0a90e07b7b upstream.

the risk of exposing module auto-loading to userspace via a crypto API,
as demonstrated by Mathias Krause:

[bwh: Backported to 3.2:
- Adjust filenames
- Drop changes to algorithms and drivers we don't have
- Add aliases to generic C implementations that didn't need them before]
