Summary:
The patch adds support for injecting errors when reading from `RandomAccessFile`
using `FaultInjectionTestEnv`. (This functionality was curiously missing
w/r/t `RandomAccessFile`, even though it was implemented for `RandomRWFile`.)
The patch also fixes up a test case in `blob_db_test` which uses `FaultInjectionTestEnv`
but has so far relied on reads from `RandomAccessFile`s succeeding even after
deactivating the filesystem.

Summary:
Cleans up some of the dependencies on test code in the Makefile while building tools:
- Moves the test::RandomString, DBBaseTest::RandomString into Random
- Moves the test::RandomHumanReadableString into Random
- Moves the DestroyDir method into file_utils
- Moves the SetupSyncPointsToMockDirectIO into sync_point.
- Moves the FaultInjection Env and FS classes under env
These changes allow all of the tools to build without dependencies on test_util, thereby simplifying the build dependencies. By moving the FaultInjection code, the dependency in db_stress on different libraries for debug vs release was eliminated.
Tested both release and debug builds via Make and CMake for both static and shared libraries.
More work remains to clean up how the tools are built and remove some unnecessary dependencies. There is also more work that should be done to get the Makefile and CMake to align in their builds -- what is in the libraries and the sizes of the executables are different.
