debian: Drop GVariant alignment patches which are no longer needed
The upstream 2.59.0 release contained commit 0f2a6c61, which automatically aligns GVariants at construction time. The realignment in the tests was a workaround for this.
See upstream issue https://gitlab.gnome.org/GNOME/glib/issues/1342.
