installer/portable: include terminfo for GNU screen and tmux

While Git for Windows does not ship with GNU screen nor tmux (commands
that allow you to multiplex several command line sessions into a single
terminal window), the use case seems to be common enough to at least
support it by shipping the necessary terminfo files.

This makes it possible to extract tmux.exe, say, from
tmux-git-2.5.94.g73b9328c-1-x86_64.pkg.tar.xz and msys-event-2-1-6.dll
from libevent-2.1.8-1-x86_64.pkg.tar.xz (both files can be downloaded
from http://repo.msys2.org/msys/x86_64/) to $HOME/bin/ and then use
tmux.exe from within Git Bash.

It would be a lot more inconvenient if the user then would also have to
download ncurses-6.0.20170708-2-x86_64.pkg.tar.xz and extract
/usr/share/terminfo/73/screen into Git for Windows's root directory
(which is typically only writable by administrators).

Those screen terminfo files weigh in with a grand total of just over
200kB unpacked (and just under 10kB compressed), meaning that there is
little cost to accommodate those use cases, either.

This closes git-for-windows/git#1341
