Fix zconfig.sh test 9

Commit ba6a240 adjusted the behavior of 'zfs create -V'.  The
caller is no longer guaranteed that udev will have finished
creating the /dev/ entries by the time to command exits.  It
is therefore required that we explicitly block waiting for
udev to settle for this test to run reliably.

Add explicit Conflicts for zfs-fuse packages

zfs-fuse provides the same commands and man page names as ZoL.
Changing the names on either side would make each incompatible with
all existing documentation about ZFS. Providing bit identical files
is not possible due to differing codebases.
