AndroidMetadataStage.PerformStage claims that all internal failures are InfrastructureFailures. This is wrong and ends up blaming infra for product problems.

As an example, see: https://bugs.chromium.org/p/chromium/issues/detail?id=729608#c5
(Bugs in android ebuilds (or dependent ebuilds) that cause dependency graph generation to fail will blame infra. This is a product failure).

This bug is to request that:
- We remove the catch-all InfrastructureFailure decorator.
- We add more fine-grained InfrastructureFailure decorators if needed.
