[PATCH v2 14/27] userdiff tests: move custom patterns into one test file

["Ævar Arnfjörð Bjarmason" <avarab@gmail.com>]

In a preceding commit the test infrastructure got rewritten so
"t/t4018/" are now normal test files which can do things like set
config, so let's make it responsible for setting up and tearing down
the config for its tests.
