software/theia: set TERMINFO

We are observing some segmentation fault with python curses applications
that might be because the TERMINFO are different from the system one.
I did not debugged, but since I set this environment variable I did not
observe any segmentation fault.

By comparing strace, the invocations seems same with or without $TERMINFO.
In both cases the termcaps from the correct ncurses are selected, this
just seem to workaround for some reason.
