test: make 'check wait' more reliable.

'recover' etc doesn't appear in /proc/mdstat immediately.
The "sync" thread must be started first.
But 'sync_action' shows it as soon as MD_RECOVERY_NEEDED is set
in the kernel.  So look there too.

Now maybe I can get rid of some of those silly 'sleep' calls.
