Clean-up manifest merge attributes.

1. Remove tools:replace in manifest files. This attribute is only needed to establish priority when two manifests are merged and have the same attribute with different values.
As this is not happening here, the attributes can be removed.

2. Some BUILD files also define a deprecated manifest merge strategy different from the android default merge strategy. For consistency these are set to "android'.
