Make SSL_get_servername work in the early callback.

This avoids early callback users writing their own SNI parser and gives us a
place to surface the server name from ESNI in the future.

Update-Note: This isn't a breaking change, but users of
SSL_CTX_set_select_certificate_cb can likely drop a bit of code after this CL.
