[15/16] fuzzy: allow substitution of AG numbers when configuring scrub stress test

Commit Message

From: Darrick J. Wong <[e-mail]>

Allow the test program to use the metavariable '%agno%' when passing
scrub commands to the scrub stress loop.  This makes it easier for tests
to scrub or repair every AG in the filesystem without a lot of work.
