Description of problem:

p11_child currently has an infinite timeout which is causing OCSP requests to fail on semi-disconnected systems with multi certificates, such as a CAC.

Version-Release number of selected component (if applicable):

OS: Red Hat Enterprise Linux release 8.5 (Ootpa)
SSSD: sssd-2.5.2-2.el8_5.3.x86_64
p11-kit: p11-kit-0.23.22-1.el8.x86_64

How reproducible:

Consistently.

Steps to Reproduce:
1. Prepare system for smart card login with a CAC.
2. Disconnect from the network
3. Attempt to login.

Actual results:

The certificate menu is presented even though the cert is specified, and login fails after PIN entry.

Expected results:

The system skips the OCSP check (if configured) due to connection timeout and proceeds onward.
