It will cause compton to print out some rudimentary diagnostics.
Also small improvements of the meson.build.

This was a dubious "fix" for a Nvidia driver problem. The problem was
never fully understood, and the then developers took a shotgun approach
and implemented xsync fences as a fix. Which somehow fixed the problem.
Again, I don't see any indication that the developers understood why
this "fix" worked.
(for details, see chjj/compton#152 and chjj/compton#181)
The driver problem should have been fixed almost 5 years ago. So this
shouldn't be needed anymore. In addition the way compton uses xsync fences
is apparently wrong according to the xsync spec (fences are attached to
screen, but compton uses them as if they were attached to drawables).
So, I will try removing it and see if anyone will complain. If there are
real concrete reasons why fences are needed, it will be brought back.
