Build with the logging-parent reusable workflows (#470)

* Build with the `logging-parent` reusable workflows

Flume no longer maintains its own checkout, JDK and Maven steps, and gains
snapshot/release deployment and reproducibility verification in exchange.

Assisted-By: Claude Fable 5 <noreply@anthropic.com>

* Skip Taildir tests on non-POSIX file systems

TaildirSource tracks files by inode, so its tests cannot pass when the
default file system lacks a `unix` attribute view (e.g. on Windows).
Document that requirement in the user guide.

* Fix race condition in TestSyslogTcpSource.testSSLMessages

The test read from the channel immediately after closing the client
socket, but the source delivers events asynchronously, so the take
could return null on slow machines (first seen on Windows CI).

Wait for the source counter with Awaitility and close the TLS socket
gracefully, flushing before close.

* Keep the client socket open until the syslog event is committed

The Windows CI logs show the TLS handshake succeeding and the
connection aborting one millisecond later: the client never reads the
TLS 1.3 session tickets sent by the server, so close() aborts the
connection with a TCP RST, which on Windows discards the syslog record
before the server reads it.
