efilinux: Explain the config file syntax and add an example
The only explanation of the config file syntax is in the commit log
that introduced it, commit 77148a3e4978 ("efilinux: Minimal
configuration file support"), so add a couple of lines to the README
describing it. Also, add an example config file.

+There is no config syntax as such. A config file is a one-line file
+that contains command line parameters. See example.cfg.
