pkcs11-tool in Jammy (opensc=0.22.0-1ubuntu2) fails with `-t` while
testing digests:
```
$ sudo pkcs11-tool -l -t
Using slot 0 with a present token (0x0)
Logging in to "Users".
Please enter User PIN:
C_SeedRandom() and C_GenerateRandom():
seeding (C_SeedRandom) not supported
seems to be OK
Digests:
all 4 digest functions seem to work
MD5: OK
SHA-1: OK
error: PKCS11 function C_DigestInit failed: rv = CKR_GENERAL_ERROR (0x5)
Aborting.
```
This works in Focal and Noble. The test command provides users with a
more firm indication that their smartcard is compatible/functional with
OpenSC; it is often used while troubleshooting other issues with
smartcards.
This particular error occurs because the RIPEMD160 hash function is not
included in OpenSSL's default provider in Jammy [1][2].
OpenSC 0.22 does not contain patches that update deprecated usage of
OpenSSL 3; they were merged for 0.23 [3][4]. This bug was fixed in that
PR (discussed in [5]).
It looks to me like this bug showed up in #1972753, although that issue
was resolved with a change of OpenSSH configuration. I'm opening this
bug report to deal specifically with pkcs11-tool.
A backport of [6] is sufficient to resolve the C_DigestInit failure.

[ Test Plan ]
Create CA & certificates for a virtual smart card as found at [1].
Follow the instructions at [2] to create a cloud-init config drive `seed.img`
with the following user-data:
```
#cloud-config
chpasswd:
expire: false
users:
- name: ubuntu
password: password
type: text
```
Launch a qemu VM with emulated smart card:
```
sudo qemu-system-x86_64 \
-enable-kvm \
-m 1024 \
-nic user,model=virtio \
- -drive file=root.img,media=disk,index=0,if=virtio \

\

```
Log in, install opensc and test the card with:
```
sudo pkcs11-tool -t
```
