use Octave system functions to avoid build failure with Qt 4 (bug #53540)

* ObjectProxy.cc (ObjectProxy::get_pixels): Use octave_sleep function rather
than QThread::msleep, which is not a public method in Qt 4.
* documentation.cc (documentation::~documentation): Use sys::recursive_rmdir
rather than QDir::removeRecursively, which does not exist in Qt 4.
