options: Allow avoiding system-wide configuration

Browse Source 
The added option SSH_BIND_OPTIONS_PROCESS_CONFIG allows to skip
processing the system-wide configuration file.  The global configuration
file is processed automatically if this option is not set as false.

This option will only be effective if set before any call to
ssh_bind_options_parse_config().
