tests/udev-test.pl: add multiple device test
Add 4 new tests using multiple devices. Number 2-4 use many
devices claiming the same symlink, where only one device has
a higher priority thatn the others. They fail sporadically with
the current code, if a race condition causes the symlink to point
to the wrong device. Test 4 is like test 2 with sleeps in between,
it's much less likely to fail.
