initramfs-framework: support force reboot if fatal error occurs

Add support for force reboot in the case of fatal error. In some cases
it's better to force reboot (especially when hw watchdog is not
engaged) instead of waiting for 3600 seconds, for example in order to
trigger some recovery procedure during next boot procedure
(after unsuccessful OTA update etc).

ALso fix indendation issues in the fatal() function implementation.
