Disable gtkdoc-check by default for now

We know the documentation is incomplete, so there seems little value
in having 'make check' tell us that. Everything except the documentation
check is expected to succeed, so it's now more useful to report test
failures in continuous integration systems, making functional
regressions more visible.
