Remove exception for lldbinit and watch apps.

When building, the app extension + app target will build such that
the app target "wins" in being the last target built.

In addition, bazel_build.py's lldbinit update logic no longer
retrieves path redirection information directly from the binaries
being debugged, so this is more likely to cause problems going
forward than it solves.
