Subject: [PATCH] ncurses: provide pkg-config alias files for libtinfo / libtic

Some build scripts (e.g. u-boot tools) look for pkg-config configuration
for libtinfo specifically. The way ncurses is configured for nixpkgs,
libtinfo and libtic functionality is provided by libncursesw, so alias
the pkg-config .pc with some symlinks.
