[Icecast-dev] https bug + fix

[Niv Sardi]

Looks good to me, it's even documented in the SSL doc:
| SSL_CTX_use_certificate_file() loads the first certificate stored in
| file into ctx. The formatting type of the certificate must be specified
| from the known types SSL_FILETYPE_PEM,
| SSL_FILETYPE_ASN1. SSL_use_certificate_file() loads the certificate from
| file into ssl. See the NOTES section on why
| SSL_CTX_use_certificate_chain_file() should be preferred.
