[pkg-apparmor] Bug#948142: apparmor: Update abstractions/ibus socket path

[Changwoo Ryu]

Package: apparmor
Version: 2.13.3-7
Severity: normal

In short, the ibus socket path in <abstractions/ibus> needs to be changed 
for the recent ibus versions like this:

 unix (connect, receive, send)
       type=stream
       peer=(addr="@{HOME}/.cache/ibus/dbus-*"),

Details:

This is follow-up to debian/patches/debian/allow-access-to-ibus-socket.patch.

In IBus upstream 1.5.21, the upstream has changed the default socket path
to"/tmp/ibus" to make it distinguishable. But it is not secure as a malicious
user can create "/tmp/ibus" with restrictive permission. In IBus upstream git
after 1.5.21, the upstream has changed the socket path to
"$XDG_CACHE_HOME/ibus" for Linux and "/tmp" for non-Linux. (See
https://github.com/ibus/ibus/issues/2095 and
https://github.com/ibus/ibus/issues/2116 for more information.) AppArmor is
Linux specific so allowing Unix socket "${HOME}.cache/ibus/dbus-*" is enough.

Debian ibus 1.5.21-5 has these changes (to fix non-linux FTBFS).

You can also remove the old socket path and then "ibus (<< 1.5.21-5)" should be
added to Breaks.
