vty: Optionally Set/replace cfg file during cmd 'write file'

This way if the process is started with no file associated (eg. no -c
param and default cfg path doesn't exist), config can be later saved
into a file by passing the parameter. Otherwise, until now this message
was displayed:
Can't save to configuration file, using vtysh.
