Ensure that Section exists on linuxconf

Browse Source 
When starting EDMC for the first time, linuxconf creates the required
file automatically but does _not_ create our config section. This causes
a keyerror on any access to config.

Simple solution, test that the section exists, if it doesnt, create it
(and backup any existing file beforehand)
