Subject: [PATCH] haltest: Add haltest.target to support HAL TEST mode

In order to support HAL TEST Mode, add haltest.target which requires
the least running processes for only haltest such as sdbd service.
So that haltest.target is based on getty.target to support the console
and then add deviced.service/ac.service for supporting sdbd service.

And reboot-haltest/reboot-normal scripts are for switching between normal
mode and HALTEST mode.

[Essential service list in haltest.target]
- dbus.service for /usr/bin/dbus-daemon
- serial-getty@.service for console
- dlog_logger.service for /usr/bin/dlog_logger
- systemd-udevd.service for /usr/lib/sytemd/sytemd-udevd
- systemd-journald.service for /usr/bin/systemd/systemd-journald
- ac.service for /usr/bin/amd is requied for deviced.service
- deviced.service for /usr/bin/deviced is required for sdbd.service
- sdbd.service for /usr/sbin/sdbd

[Script commands to switch between Normal and HALTEST mode]
- reboot-haltest switches from Normal to HALTEST mode.
- reboot-normal switches from HALTEST to Normal mode.
