Wait up to timeout seconds for udev devicezfs-0.5.1

Occasional failures were observed in zconfig.sh because udev
could be delayed for a few seconds.  To handle this the wait_udev
function has been added to wait for timeout seconds for an
expected device before returning an error.  By default callers
currently use a 30 seconds timeout which should be much longer
than udev ever needs but not so long to worry the test suite
is hung.
