net/xrdp{,-devel}: Update to 0.9.6

[meta]

Summary

I'm trying to use Phabricator.

• mark -devel port as IGNORE since net/xrdp has been updated
• s/XRDP/xrdp/ in pkg-message, upstream usually spell it lowercase

x11-servers/x11rdp: remove port

This port is only required by net/xrdp 0.6.2. Since net/xrdp has been
updated to 0.9.6, it is no longer required any other port and not useful
with standalone at all. 0.9.1 or later uses x11-drivers/xorgxrdp instead.

Remove duplicate entry on devel/tesla

I submitted this to lean how to use Phabricator. Cloding this since this diff is already approved by hrs.
Next time I'll use Phabricator for mentor-mentee review.
