Add com.google.pixel.camera.hal.manifest to build number allowlist

So that it can be removed from the genrule sandboxing allowlist.
Because this is an internal module, I'm submitting this allowlist
addition first, then will make the genrule use it, then will remove
it from the sandboxing allowlist.
