Fix cache lock for image not consistent

Currently 2 external (file) locks with different name
are created to protect image concurrent access for libvirt driver.
This may lead to image corruption in rare case. This patch change
the lock file name from nova-_var_lib_nova_instances_base_xxxx
to nova-xxxx to make the lock name consistent
