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'.

```

```

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.

```
