eina_debug: switch to vpath

Summary:
eina debug was using the xdg runtime dir in a wrong manner. Since the
directory should be only used by the user, and the directory should be
be subject of any other usage. Additionally, apps tend to create files
like: $XDG_RUNTIME_DIR/foo.bar which is probebly not what you want in
$HOME.
