can now be installed.

## Description:

This update for openCryptoki fixes the following issues

Security issue:

  * CVE-2026-40253: Updated fix for malformed BER-encoded cryptographic objects
    (bsc#1262283).

Non security issue:

  * Refactored .spec file to fully support transactional and immutable operating
    systems (jsc#PED-14609):
  * Migrated user and group creation (pkcs11, pkcsslotd) from imperative %pre
    shell commands to declarative systemd-sysusers configuration.
  * Replaced manual /var directory tracking and %ghost directives with
    comprehensive systemd-tmpfiles configurations.
  * Implemented dynamic, architecture-specific tmpfiles.d generation to properly
    provision hardware-specific token directories (e.g., ccatok, ep11tok, lite,
    and HSM_MK_CHANGE).
  * Fixed permissions for /run/opencryptoki within tmpfiles.d to ensure the
    daemon can successfully drop privileges and bind its communication socket.
  * Moved 32-bit and 64-bit shared library symlink creation (such as
    PKCS11_API.so, stdll, and methods) from %post scriptlets into the %install
    phase, ensuring they are correctly packaged and tracked on the read-only
    /usr partition.
  * Removed legacy /etc/pkcs11 bash migration logic from %post, replacing it
    with a declarative tmpfiles.d symlink rule.
  * Cleaned up scriptlets to only execute transaction-safe macros (such as
    ldconfig and systemd service handlers).
