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.
