This needs to check the version running on the server.

Even better would be to run the sanity-scrub and sanity-LFSCK scripts on the server, so we don't need to check the server version in all of the new tests.

[Andreas Dilger]

I think there are two tasks here:

• fix the master test scripts to use --dryrun on again, so they work with 2.5.x tests. This part would be good to do before 2.6 is released so we don't have ongoing interop test failures.
• backport the parts of http://review.whamcloud.com/9989 that allow --dryrun to be used without an option, and http://review.whamcloud.com/10091 to fix the lfsck_start usage to b2_5.

Here is the patch to use --dryrun on/off again in master sanity-scrub.sh test_15 scripts: http://review.whamcloud.com/10621

Patch landed to Master.
