access: Fix nwfilter-binding ACL access API name generation

https://bugzilla.redhat.com/show_bug.cgi?id=1611320

Generation of the ACL API policy is a "automated process"
based on this perl script which "worked" with the changes to
add nwfilter binding API's because they had the "nwfilter"
prefix; however, the generated output name was incorrect
based on the remote protocol algorithm which expected to
generate names such as 'nwfilter-binding.action' instead
of 'nwfilter.binding-action'.

This effectively changes src/access/org.libvirt.api.policy entries:

org.libvirt.api.nwfilter.binding-create ==>
org.libvirt.api.nwfilter-binding.create

org.libvirt.api.nwfilter.binding-delete ==>
org.libvirt.api.nwfilter-binding.delete

org.libvirt.api.nwfilter.binding-getattr ==>
org.libvirt.api.nwfilter-binding.getattr

org.libvirt.api.nwfilter.binding-read ==>
org.libvirt.api.nwfilter-binding.read
