qemu: Backport malloc-trace disabling
Allocation tracing has been removed from GLib 2.46 and trying to use it results in an ugly warning: Backport patch to not use it in Qemu. Signed-off-by: Jussi Kukkonen <jussi.kukkonen@intel.com> Signed-off-by: Ross Burton <ross.burton@intel.com>

+From 98cf48f60aa4999f5b2808569a193a401a390e6a Mon Sep 17 00:00:00 2001

+Subject: [PATCH] trace: remove malloc tracing
+
+The malloc vtable is not supported anymore in glib, because it broke
+when constructors called g_malloc. Remove tracing of g_malloc,
+g_realloc and g_free calls.
+
+Note that, for systemtap users, glib also provides tracepoints
+glib.mem_alloc, glib.mem_free, glib.mem_realloc, glib.slice_alloc
+and glib.slice_free.
