sfeed_update: fix message when the configuration file does not exist

When sfeed_update was called without using a parameter and it used the default
and this path did not exist it would incorrectly print:

	Configuration file "" does not exist or is not readable.
	See sfeedrc.example for an example.

Make the error message a bit shorter too.

This was a partial regression of commit df74ba274c4ea5d9b7388c33500ba601ed0c991d
