Fix paths: test/udev-test.pl now works under sudo make distcheck

We move the test-udev.c and test-libudev.c from src/test to test.
This corrects the a problem with hard coded relative paths finding
the test/test/sys directory created by test/udev-test.pl.

This commit draws heavily from nvinson patch in
