[ktap] [PATCH 2/2] uprobes: fix calling of write_uprobe_event() with NO_LIBELF

After 21bbbbf6c7a3f94583b0660b5db33870b6d1232e ("Support uprobe/sdt
symbol glob match completely") write_uprobe_event() accept symbol name,
so we need to give it.
While we don't have libelf, just pass address in hex as string.
