Add installation of the udev rules if appropriate. With a normal 'make

install', the udev rules will be installed if udev version is >= 059;
otherwise, the hotplug rules get installed.

When 'make dist' is done, we set a variable so that both hotplug and
udev rules are installed into the dist tarball.  install.sh then takes
care of picking the proper rules.

Also changes the hotplug check to look for a proper udev version
