stand: More sensible defaults when ConOut is missing
When ConOut is missing, we used to default to serial. Except we did it
in the worst way possible by just setting the howto bits and not
updating the console setting, which lead to weird behavior where we'd
get some things on the video port, others on serial.
Instead, set console to "efi,comconsole" for this case. Also set
RB_MULTIPLE always (so we get dual consoles from the kernel) and or in
RB_SERIAL when we can't find GOPs that suggest the precense of a video
console. This will put output in the most places and have a sensible
default for 'primary' console.

One possibly surprising result of this is that I did not get dual console
output on my rpi after this. (Curiously this only affected my arm64 image
but not my armv7 image.) Loader output goes to both, but kernel output is
only on the video console (which I don't normally use for my pi). (Also,
none of the ANSI escape sequences used by the loader work on the pi's video
console, so once the menu starts it just looks like raw ANSI code garbage
until the kernel starts booting.)
Not sure if this warrants UPDATING as the effect is that the serial console
seems to stop working? The lack of working dual console output is perhaps
the only real bug. Not sure what is up there.
