Fix TERMINFO path for Nix release builds on Linux

ncurses in Nix is built with a TERMINFO path that references `/nix`.
This causes the binaries fail when ran on non-nix systems, unless
TERMINFO=/usr/share/terminfo is exported. This patches the binaries
to use a more sensible default TERMINFO path.
