fix: name cards by files no menu rewrites

A KNULLI card renamed in its menu was read as a Batocera SHARE drive.
KNULLI is now named by about.info first, Batocera by its own hostname,
and a drive two systems fit is said instead of guessed. Runs without
questions see mounted cards as the screen does and stop on two setups.
The card marker table of the wiki is generated.
