While working on #3345, I realized that there were a couple of issues with the curl_global_sslset() when built with a single SSL backend, resulting in an incorrect error messages in one case, and in another case an error when we should have succeeded.

This PR fixes both issues.

curl_global_sslset(): id == -1 is not necessarily an error 
It is allowed to call that function with id set to -1, specifying the
backend by the name instead. We should imitate what is done further down
in that function to allow for that.

curl_global_sslset(): fix wrong return value 
When compiled with a single SSL backend, Curl_ssl is never set to
Curl_ssl_multi, but to that single backend from the beginning.

When the caller tries to set the SSL backend to a different backend than
the one that was compiled in, in this scenario we should not say that it
is too late to set the SSL backend, but that it is an unknown backend to
begin with.
