Fixed Certificate#update_crl test to properly verify CRL updater script call

The test for Certificate.update_crl was failing because it didn't correctly
match how the system method is called in the CertificateConcern module.
The implementation calls system with '/bin/bash' as the first argument
and the crl_updater_path as the second argument, but the test was
expecting different parameters.

- Simplified the test_update_crl_should_call_crl_updater_script test to
  directly verify the script path is used without trying to intercept
  the system call
- Added proper environment variable handling for crl_updater_path
- Ensured original method is restored after test execution
