Inherit hostflags verify params even without hosts

X509_VERIFY_PARAM_inherit() now copies hostflags independently of hosts.

Previously hostflags were only copied when at least one host was set.
Typically applications don't configure hosts on SSL_CTX. The change
enables applications to configure hostflags on SSL_CTX and have OpenSSL
copy the flags from SSL_CTX to SSL.
