fsck: Add a -r option to report memory and runtime statistics
This patch adds a "-r" option to report statistics for each fsck run.
It gathers the statistics via wait4() and rusage and reports exit
status, system and user CPU time, elapsed wall-clock time and the max
RSS.
[kzak@redhat.com: - rebase to the latest code,
- report all on one line,
- use "real" rather than "elapsed"]
