arti 41e21b6494 udpstream: reboot works on the real unit (88 s), and correct the earlier call
Issued while the payload owned the LANCE: the reply arrived, control went to
0x3F200040, the screen went black -- and the OS was back 88 s later.  Port 771
reopened on its own, the unit answered ping, and a VRAM screenshot shows the
Terminal Manager with the right MAC/IP/LAT name and the clean-boot
"Ethernet Port Error - 24" banner.  A taken-over unit can therefore hand
itself back without a power cycle.

An earlier reading of the same run reported "black and hung, needs a power
cycle".  That was a single observation taken inside the ~90 s POST window.
The black screen is the reset path reprogramming the board/video window
(0xC00000B0, 0xC0000100) and not re-enabling the display until POST ends.

vtcmd.py reboot now says how long it takes and warns not to power cycle
during it, instead of refusing to run.
