profile.d/toolbox.sh doesn't take into account TERMINFO_DIRS

[tristan957]

Describe the bug
TERMINFO_DIRS is another way to inform tools like tput(1) of terminfo(5) entries. Because the script doesn't take it into account, you get an error on startup like Error: terminfo entry not found for xterm-ghostty.

Steps how to reproduce the behaviour

1. Store a terminfo entry in a non-default directory, like $XDG_DATA_HOME/terminfo
2. Enter a toolbox container

Expected behaviour
The script should read TERMINFO_DIRS.

Actual behaviour
TERMINFO_DIRS is not read.

openssl is the container. gonk is the host.

Although I guess this script is source before my bashrc where I set the relevant environment variables. Hmm. Interested to hear the thoughts of others.
