Makefile: remove -DXLOGGING compiler flag

This was added back in 2011 (https://crrev.com/c/4137) in conjunction
with moving the library to use the X11 xf86MsgVerb logging function
(which avoided uses of malloc, a source of issues on X11 at the time).
We no longer use this logging function, and the library is no longer
used with X11 display servers, so we should be able to remove this now.
