Once in bionic, we will want to SRU to xenial so that all snaps that are
built with a xenial stack get an updated libibus.

ibus_bus_init does an unconditional call to chmod on
Status in ibus:
Status in ibus package in Ubuntu:
This was spotted by jdstrand when running the chromium snap, which
recently enabled ibus support (https://forum.snapcraft.io/t/cant-use-
audit: AVC apparmor="DENIED" operation="chmod"
pid=16919 comm="chromium-browse" requested_mask="w" denied_mask="w"
The code that calls chmod is in ibus_bus_init:
ibus_bus_init (IBusBus *bus)
path = g_path_get_dirname (ibus_get_socket_path ());
g_mkdir_with_parents (path, 0700);
g_chmod (path, 0700);
This could be avoided by checking first the file mode bits on that
directory, and do the g_chmod call only if ≠ 0700.
