    oeqa/controllers: Add test target for Systemd-boot
    
    A new test target is neede to test Systemd-boot similar
    to gummiboot. Created a copy of GummibootTarget class
    and named as SystemdbootTarget, at this point the
    gummibootTarget will remain until documentation is
    updated with new systed information.
