ncurses-libs: provide libncurses.so.5
https://github.com/void-linux/void-packages/pull/23862

Description:
@q66 can you please allow this symlink at least?

I state my case:

a. I need /usr/lib/libncurses.so.5 to run a binary (fwiw, megacli to manage a LSI raid controller -- unfortunately there's no other way to manage the raid arrays without rebooting to bios)

b. This binary runs without any problem with the symlink

c. I think this is expected since the ncurses 6 library is both API and ABI compatible with ncurses 5, according to its own documentation:

> This release is designed to be source-compatible with ncurses 5.0 through 6.1; providing extensions to the application binary interface (ABI). Although the source can still be configured to support the ncurses 5 ABI, the reason for the release is to reflect improvements to the ncurses 6 ABI and the supporting utility programs.

d. Someone else requested it on reddit (https://www.reddit.com/r/voidlinux/comments/hprhjp/where_to_download_libncursesso5/)

I'm not sure about all the other symlinks that https://github.com/void-linux/void-packages/commit/854828d619792969aef4315747c768a618434acd removed, an alternative would be to revert that one and apply https://github.com/void-linux/void-packages/pull/23660/commits/37f47318107975b56192a84fec9502b534628f4d from PR #23660 instead.
