initrd/bin/kexec-save-default: remove mount-usb --mode rw and dmesg.txt output to usb thumb drive

Really handy btw. Would be nice to add that into sysrq magic to output to usb thumb drive and have ctrl-alt-delete output dmesg to external storage when in debug mode. Would work also for headless debug when porting
