Subject: [PATCH] Add runtime library version information to verbose pkg -vv

With pkg using external library dependencies, exact runtime information of these libraries is needed for efficient support.

Add pkg_libversion to libpkg to report its own version.
Report libpkg, libcurl, libarchive, sqlite and openssl runtime versions in verbose show_version_info.
