[PATCH] xfree86: rename Xorg.bin to Xorg

[Peter Hutterer]

If the suid wrapper is enabled, /usr/bin/Xorg is just a shell script that
execs either /usr/libexec/Xorg.bin directly or the Xorg.wrap binary which then
execve's /usr/libexec/Xorg.bin.

Either way, we end up with Xorg.bin, which is problematic for two reasons:
* ps shows the command as Xorg.bin
* _COMM and _EXE in systemd's journal will both show Xorg.bin as well

There's not much we can do about the path, but having the actual command stay
as Xorg means better compatibility to existing scripts. And, the reason for
this patch: the command
   journalctl _COMM=Xorg
works universally, regardless of whether the wrapper is used or not.

 The Xorg X server may need root rights to function properly. To start the

 By default Xorg.wrap will autodetect if root rights are necessary, and
 if not it will drop its elevated rights before starting the real X server.
