Revert 63600 - Thread IO safety: annotate file_util, and block IO thread from doing IO

Reverting because this breaks the ChromiumOS (dbg) builder.

- Mark functions in file_util_posix as requiring permission to perform
  disk actions.
- Mark the IO thread as disallowed from performing disk actions.
- Temporarily work around the protections in places where we currently
  have bugs.

TEST=no dchecks in debug builds
