Override TERMINFO_DIRS to prefer host terminfo files over builtin ones

[sandorex]

This would make using terminals like kitty, wezterm, etc that use custom terminfo painless and possibly prevent issues with mismatch of terminfo versions as the terminfo that comes with the terminal is used

Would this also be required for host's ~/.terminfo as well? If so, I'd highly suggest to also provide a mapping for this. :)

I think it is used by default by ncurses if it exists but im not sure if the TERMINFO_DIRS modifies the priority, ill have to check

[sandorex]

I have confirmed that ~/.terminfo is preferred by default so there is no need to add it

I have placed same terminfo file in ~/.terminfo and added env TERMINFO_DIRS=/var/run/host/usr/share/terminfo/:/usr/share/terminfo and it still takes it from ~/.terminfo, as always this depends on the application following the convention

EDIT: GH automatically closed the PR, my bad

Isn't '--env=TERMINFO_DIRS=/app/share/terminfo:' enough to work? Could you try and let me know, please?
