bootctl: replace "type" with "source" in output

I think this is more useful (because it's easy to stick the path into an editor command
when one wants to change the options or inspect the files), and more self-explanatory.

Example output:

 * bootctl
   - verify that the files boot entries point to exist
   - recognize the case when not booted on EFI
-  - specify paths for boot entries
 
 * maybe do not install getty@tty1.service symlink in /etc but in /usr?
