feat: run the handheld launchers in the tui

The PortMaster port now starts install.py --tui on the console (or in
foot or xterm under a compositor), with gptokeyb in kill mode on the
installer's path, retrobios.gptk, TERM=linux and a Terminus font, and
puts the console, font and mapper back on exit. pugwash screens stay as
the fallback where no terminal can show, and start in no-check mode so
PortMaster's A/B fix applies. Without a network, every launcher installs
from a pack found on the card or names the pack and the folder.

Adds launchers for Batocera and Knulli (Ports, evmapy .keys), muOS
(.muxapp in muxterm with gptokeyb2) and the Tools menu of ArkOS,
dArkOS, ROCKNIX, JELOS and AmberELEC, built by build_port.py with the
pinned installer and tested on a simulated device.
