Zbigniew Jędrzejewski-Szmek d407638382 test/udev-test: gracefully exit when imports fail 
In Fedora rawhide various perl modules are now available as separate
packages that are not pulled in by dependencies. If we don't have some
package, skip the tests.

This ugly code is apparently the way to do conditional imports:

# udev test
#
# Provides automated testing of the udev binary.
# The whole test is self contained in this file, except the matching sysfs tree.
# Simply extend the @tests array, to add a new test variant.
#
# Every test is driven by its own temporary config file.
# This program prepares the environment, creates the config and calls udev.
#
# udev parses the rules, looks at the provided sysfs and
# first creates and then removes the device node.
# After creation and removal the result is checked against the
# expected value and the result is printed.
