Version 1.0.27: Fix launch in Ubuntu 17.04

Browse Source 
Ubuntu 17.04 launch results in segfault if the build was done
by GCC 6.2 (works fine with GCC 4.9). Backtrace shows that it
crashes in gtk_init_check() call somewhere in libmirclient and
tests show that it works fine with GDK_BACKEND=x11.

So we use gdk_set_allowed_backends() method to explicitly state
that we support only "x11" GDK backend, that way it doesn't try
to use libmirclient and it does not crash.

Fix #3176 #3162
