[PATCH] package.bbclass: Fix do_package variable dependencies

[Richard Purdie <richard.purdie@linuxfoundation.org>]

When the do_package function was split into different sections, the vardeps
were not updated to match meaning some function changes weren't reflected
in the sstate checksums. Fix this.
