MDEV-14974: --port ignored for --host=localhost

Problem:
=======
MariaDB's command line utilities (e.g., mysql,
mysqldump, etc) silently ignore connection
property options (e.g., --port and --socket)
when protocol is not explicitly set via the
command-line for localhost connections.

Fix:
===
If connection properties are specified without a
protocol, override the protocol to be consistent.
For example, if --port is specified, automatically
set protocol=tcp.

Caveats:
=======
 * When multiple connection properties are
specified, nothing is overridden
 * If protocol is is set via the command-line,
its value is used

Reviewers:
========
