Revert "Fix error checking in MemoryFile."

This reverts commit 2142c2cf6ffc0979fff7d0312fd6f90ca6c08a19.
Fix android.os.cts.MemoryFileTest#testLength
ActivityManager: Fix monkey tests

Change I30e38c6c27d339d55a8f9a0f4106185356a9b9a0 (adding ordered
broadcast prioritization) adds the assumption that every broadcast
generator has a full-fledged caller app, which isn't true for
monkey-created tests. Make sure the caller is a full app before
checking if it is AID_SYSTEM to avoid an NPE

Fixes com.android.cts.monkey.*
