It was missing while detecting `wolfSSL_DES_ecb_encrypt`,
`wolfSSL_BIO_new` and `wolfSSL_BIO_set_shutdown`.
We have not seen it causing issues in stable wolfSSL releases as of
v5.7.4, until a recent commit in wolfSSL master, which broke detections:
```
curl/CMakeFiles/CMakeScratch//CheckSymbolExists.c:8:19: error: ‘wolfSSL_BIO_new’ undeclared (first use in this function); did you mean ‘wolfSSL_CTX_new’?
curl/CMakeFiles/CMakeScratch//CheckSymbolExists.c:8:19: error: ‘wolfSSL_BIO_set_shutdown’ undeclared (first use in this function); did you mean ‘wolfSSL_set_shutdown’?
```
This in turn disabled `HTTPS-proxy` and failed related pytests:

The wolfSSL build says:
```
Note: Make sure your application includes "wolfssl/options.h" before any other wolfSSL headers.
You can define "WOLFSSL_USE_OPTIONS_H" in your application to include this automatically.
```
This patch makes sure to follow this rule across the curl codebase.
Also:
- include `wolfssl/options.h` first in `lib/vtls/wolfssl.c`.
It was preceded by `wolfssl/version.h`, which did not cause issues.
