added live_rw support

There's a need for a separate boot target since persistent storage is way slower than tmpfs indeed; usbflash has a tendency for huge performance drops given simultaneous writes in addition to reads which are the bottleneck already. make-initrd-propagator 0.18 introduced ext4 rw slice, so the corresponding kernel module needs to be included into stage1; see also #28289. NB: not available on x86_64-efi (or hybrid GPT to be strict) due to fragility of the hack being made: parted(8) panics upon seeing that, and good ol' fdisk is unable to treat it. NB: use/live/rw use/rescue/rx use/syslinux/ui/gfxboot are unlikely to play very nice together due to the latter's magic l10n: "session" label is taken by live_rw config snippet and *is* translated in design-bootloader-source; OTOH "rescue_session" is *not*.
