Add extended_primary_loader to autobuild.

* Build fat1x, fat32, cdfs, after_win loaders.
* Set use_lba=1 by default in fat32 loader.
* Build kolibri.raw: flash / hdd image.
* Add example config.ini file.
* Add an option (config file and screen) to not load ramdisk image.
* Add an option (config file only) to set /sys path.

Now you can boot without a ramdisk from a storage that is supported
by the kernel itself, i.e. without loadable drivers. Thus you can not
load the system without a ramdisk from SATA/AHCI and USB drives.
