[PATCH 1/2] ncurses: put symlinks to basic terminfo files in ncurses-terminfo-base package

[Rasmus Villemoes <ravi@prevas.dk>]

From: Rasmus Villemoes <ravi@prevas.dk>

With only the ncurses-terminfo-base package installed (i.e. not the
full ncurses-terminfo), systemd prints

  Terminfo xterm-256color not found for /dev/console

That is despite 'xterm-256color' being one of those basic terminfo
files that are manually split off and into the terminfo-base package,
and placed under /etc/terminfo/. The reason is that systemd only looks
in /usr/share/terminfo (see their have_terminfo_file() in
src/basic/terminal-util.c).

Make sure that applications that only look in /usr/share/terminfo do
find the basic terminfo files by packaging the symlinks along with the
pointed-to files.
