    openssl: conditionally disable engine section
    
    Currently, the build option to enable/disable engine support isn't
    reflected in the final '/etc/ssl/openssl.cnf' config. It assumes `engines`
    is always enabled, producing an error whenever running any
    commands in openssl util or programs that explicitly use settings
    from '/etc/ssl/openssl.cnf'.
    
    ```
    ➤ openssl version
    FATAL: Startup failure (dev note: apps_startup()) for openssl
    307D1EA97F000000:error:12800067:lib(37):dlfcn_load:reason(103):crypto/dso/dso_dlfcn.c:118:filename(libengines.so):
    Error loading shared library libengines.so: No such file or directory
    307D1EA97F000000:error:12800067:lib(37):DSO_load:reason(103):crypto/dso/dso_lib.c:152:
    307D1EA97F000000:error:0700006E:lib(14):module_load_dso:reason(110):crypto/conf/conf_mod.c:321:module=engines, path=engines
    307D1EA97F000000:error:07000071:lib(14):module_run:reason(113):crypto/conf/conf_mod.c:266:module=engines
    ```
    
    Build should check for the `CONFIG_OPENSSL_ENGINE` option, and comment out `engines`
    if not explicitly enabled.
    
    Example:
    ```
    [openssl_init]
    providers = provider_sect
    ```
    
    After this change, openssl util works correctly.
    
    ```
    ➤ openssl version
    OpenSSL 3.0.14 4 Jun 2024 (Library: OpenSSL 3.0.14 4 Jun 2024)
    ```
