When running the zconfig.sh, zpios-sanity.sh, and zfault.sh
from the installed packages the 90-zfs.rules can cause failures.
These will occur because the test suite assumes it has full
control over loading/unloading the module stack. If the stack
gets asynchronously loaded by the udev rule the test suite
will treat it as a failure. Resolve the issue by disabling
the offending rule during the tests and enabling it on exit.

Just like zconfig.sh the zpios-sanity.sh tests should run in a
sanatized environment. This ensures they never conflict with an
installed /etc/zfs/zpool.cache file.
This commit additionally improves the -c cleanup option. It now
removes the modules stack if loaded and destroys relevant md devices.
This behavior is now identical to zconfig.sh.
The zpios-sanity.sh script should return failure when any
of the individual zpios.sh tests fail. The previous code
would always return success suppressing real failures.
