libxl: add option to choose who executes hotplug scripts

Add and option to xl.conf file to decide if hotplug scripts are
executed from the toolstack (xl) or from udev as it used to be in the
past.

This option is only introduced in this patch, but it has no effect
since the code to call hotplug scripts from libxl is introduced in a
latter patch.

This choice will be saved in "libxl/disable_udev", as specified in the
DISABLE_UDEV_PATH constant.
