[Buildroot] [git commit branch/2019.02.x] package/civetweb: fix link failure due to missing OpenSSL dependency

[Peter Korsgaard]

commit: https://git.buildroot.net/buildroot/commit/?id=18f8a9d00c340c5c1ffe23ce8cafedebd5e42562
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/2019.02.x

During linking one OpenSSL dependecy is missing(-latomic) on linking
library list.

- Substitute explicit library list with `pkg-config libssl` when
  BR2_PACKAGE_OPENSSL is enabled. In such way all needed libraries
  will be included in linking list.

- Add also `host-pkgconf` to CIVETWEB_DEPENDENCIES if
  BR2_PACKAGE_OPENSSL is enabled to make it available for previous
  point.
