Ensure bpglob is built early

This matches the change to blueprint's blueprint_impl.bash:
https://github.com/google/blueprint/pull/213

It allows us to run bpglob during the two bootstrap phases, so we're
never running minibp or the primary builder in a later phase than
normal.

Also removes the dependency on out/soong/build.ninja from the main
phase, since it's never generated by the main phase anymore, and is
tripping the dangling dependency checks.
