xorg 1.18.1 breaks log file renaming

[Antoine Martin]

Something changed since 1.18.0 and it ain't good.
The xorg server will print:

Failed to rename log file "/home/antoine/.xpra/Xorg.S10814.log" to "/home/antoine/.xpra/Xorg.S10814.log": No such file or directory

Which is just plain stupid, no idea why it tries to do that.

This in turn causes us some problems when we try to rename the logfile ourselves.
r12500 + r12501 try to continue anyway despite the missing log file - and will need to be backported.

Re-opened the upstream ticket which caused this breakage: ​https://bugs.freedesktop.org/show_bug.cgi?id=93212#c5

New seperate upstream ticket ​https://bugs.freedesktop.org/show_bug.cgi?id=95234.

Not much we can do at this end, so closing.
