[Buildroot] [git commit branch/2019.02.x] package/cups: store web-interface files under /usr/share/cups/doc-root

[Peter Korsgaard]

commit: https://git.buildroot.net/buildroot/commit/?id=822067294a9949fa79e5ff6c6d8d6a434ef4a7a0
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/2019.02.x

The web-interface files (~1.8MB) are by default installed under
/usr/share/doc/cups, which is unfortunate as Buildroot removes usr/share/doc
in target-finalize, breaking the webui.

As a fix, store the web-interface files under /usr/share/cups/doc-root,
similar to how it is done in Debian.
