test(logback): Move the logback sample's system test into sentry-logback

The test now configures the appender from XML in-process and sends to
MockSentryServer, so it runs as part of :sentry-logback:test instead of
needing the Python runner and a shadow JAR. It also checks that the XML
contextTag reaches the event.

The logback sample has no tests left, so its system-test wiring, CI
matrix entry and runner entry are removed.
