easyrsa_openssl(): Move saving SAFE SSL config name to correct place

Saving the name of the fully expanded Safe SSL config means that this
config file only has to be built once.

The assignment of working_safe_ssl_conf, which signifies that a Safe
SSL config has already been created, was set too late, which caused
it to be set even if the Safe SSL config had not been created.

Also, include a final check in verify_working_env() to ensure that
working_safe_ssl_conf has not been set prior to executing the issued
command, eg. build-ca.

Also, improve verbose messages and comments.
