[Spice-devel] [PATCH spice-common] ssl-verify: use more explicit error message

[Marc-André Lureau]

When the server certificate is not being signed by the provided CA,
the SSL debug message is currently for example:

ssl_verify.c:428:openssl_verify: openssl verify:num=19:self signed
certificate in certificate chain:depth=1:/C=IL/L=Raanana/O=Red
Hat/CN=my CA

Add a more explicit debug message too, as requested in bug:
