IMPALA-5769: Add periodic minidump cleanup

Minidumps can be written by sending SIGUSR1 to our daemon processes.
That way, an arbitrary number of minidump files can be created. This
change adds minidump cleanup to the periodic log file cleanup to
effectively bound the maximum number of minidumps we keep around.

> Minidumps can be triggered by sending SIGUSR1 to a daemon process. This can lead to an arbitrary number of minidumps on the system. We should clean them up periodically, similar to how we're rotating log files.
