qom: strdup() target property name on object_property_add_alias()

Browse source 
With this, object_property_add_alias() callers can safely free the
target property name, like what already happens with the 'name' argument
to all object_property_add*() functions.

Backports commit 1590d266d96b3f9b42443d6388dfc38f527ac2d8 from qemu
