apparmor: fix ptrace rules with kernel 4.18
Due to kernel upstream change 338d0be4 ("apparmor: fix ptrace read check")
libvirt now hits apparmor denies like:
  apparmor="DENIED" operation="ptrace" profile="/usr/sbin/libvirtd"
  pid=4409 comm="libvirtd" requested_mask="read" denied_mask="read"
  peer="libvirt-14e92a75-7668-4b97-8f92-322fc1b9c78a"

Extend the ptrace rule to also allow 'ptrace (read)' for libvirtd to work
with these newer kernels.

0041eda1e4 util: eventpoll: Survive EBADF on macOS
Fixes:
https://www.redhat.com/archives/libvir-list/2017-January/msg00978.html

QEMU is probed through monitor fd to check capabilities during libvirtd init.
The monitor fd is closed after probing by virQEMUCapsInitQMPCommandFree
that calls virQEMUCapsInitQMPCommandAbort that calls qemuMonitorClose,
the latter one notifies the event loop via an interrupt handle in
qemuMonitorUnregister and after then closes monitor fd.

There could be a case when interrupt is sent after eventLoop is unlocked
but before virEventPollRunOnce blocks in poll, shortly before file
descriptor is closed by qemuMonitorClose. Then poll receives closed monitor
fd in fdset and returns EBADF.

EBADF is not mentioned as a valid errno on macOS poll man-page but such
behaviour can appear release-to-release, according to cpython:
https://github.com/python/cpython/blob/master/Modules/selectmodule.c#L1161

The change also fixes the issue in qemucapabilitiestest. It returns
Bad file descriptor message 25 times without the fix.

6ef65e3c96 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 ==>
