See the attached patch for a fix which works with both old and new
ncurses-base versions.

I have reported the rather surprising tic behavior at
https://lists.gnu.org/archive/html/bug-ncurses/2023-07/msg00000.html.

Cheers,

Subject: [PATCH] Write the vt102-di terminfo entry to /usr/share/terminfo

This is the location where the all the other terminfo files are since
with ncurses-base 6.4+20230603.  Also create the directory in advance,
because tic does not create multiple levels of directories and would
fail if an older ncurses-base version is installed at build time.

Closes: #1040048
