Description

If you start Kudu with the log directory configured to a directory with inappropriate permissions, you currently get an error like:

F1026 17:55:59.784801 22950 master_main.cc:68] Check failed: _s.ok() Bad status: IO error: Unable to delete excess log files: glob failure: 2

This is hard to understand. We should surface a better error message.
