Add auto-login getty services and empty root password
Add getty@.service and serial-getty@.service files to enable root auto-login on tty1 and ttyS0 terminals. Configure systems to use empty root passwords by default across azl3, emt3, and elxr12 platforms. Modified imageos.go to handle empty password cases by deleting passwords when none is set. The changes allow for iso initrd automatically log in and start installer scripts. Signed-off-by: Yu, Fei <fei.yu@intel.com>
