Ncursesw should link with tinfow.

[iandinwoodie]

This patch is a response to issue #219. Ncursesw was linking with tinfo when it should have been linking with tinfow.

This issue is not unique to cgdb. I've included a brief list of reference issues and patches below:

[02/03/2017] - A similar problem occurred in the tig repository (issue 568).
[04/11/2017] - The issue was in tig by using tinfow with ncursesw (pull request 685).
[03/26/2018] - The seeming exact problem we are seeing surfaced as a Gentoo bug (bug 651552).
[03/31/2018] - The Gentoo solution for mutt matched the change set for tig (attachment 526196).
[10/21/2018] - We see a similar patch for gdb on Gentoo. (commit 63d9497).

Symptoms and solution are pretty straight forward. @jgehrig sorry for the delay. Can you please test this on your Gentoo machine and report back. Additionally, if it is successful, can you include the updated ldd output in a comment on this PR.

Thanks @iandinwoodie!

Sure, I can test and provide ldd output.

I don't have access to that machine right now... I will take a look at this Monday.

Great, please confirm and then we'll integrate in master.
