osslsigncode is crashing for me when used with libengine-pkcs11-openssl
on Ubuntu 24.04, e.g. with Google Cloud KMS PKCS#11 provider:

```
osslsigncode sign \
    -pkcs11engine /usr/lib/x86_64-linux-gnu/engines-3/pkcs11.so \
    -pkcs11module $PWD/libkmsp11-1.7-linux-amd64/libkmsp11.so \
    -certs cert.crt -key 'pkcs11:object=some-key' -h sha256 \
    -t http://timestamp.digicert.com \
    -in test.exe -out test-signed.exe
```

I think this is the following issue and fix:
* https://github.com/mtrojnar/osslsigncode/issues/388
* https://github.com/OpenSC/libp11/pull/554

Which should be considered for back porting or updating libp11 as this
is a crash bug that prevents this usage of osslsigncode with no
workaround.
