fix(@angular/cli): keep cli package first in update package group metadata

The `ng update` command will use the first element in the `packageGroup`
metadata data within `package.json` for display purposes. The newly
introduced `@angular/build` package was initially added alphabetically
but this interfered with the first element position.

(cherry picked from commit 3e07f5e)
