Add proper udev library context initialization and finalization to liblvm.

Browse Source 
This was missing in liblvm and it caused all udev-related operations to
not take effect when using liblvm, e.g. obtaining the list of devices from udev
db instead of scanning the whole /dev which also recreated the .cache as a side
effect. This was also the case with udisks-lvm-pv-export prober which is run
from within udev rules whenever the CHANGE event is fired.
