iproute2: tc: fix missing em_ipset module

Feature detection doesn't recognize ipset v7 use on kernel v5.x systems
and thus disables the tc ematch function em_ipset.

- backport patch:
  * 002-configure-support-ipset-v7.patch:
    650591a7a70c configure: support ipset version 7 with kernel version 5

+Subject: [PATCH] configure: support ipset version 7 with kernel version 5
+
+The configure script checks for ipset v6 availability but doesn't test
+for v7, which is backward compatible and used on kernel v5.x systems.
+Update the script to test for both ipset versions. Without this change,
+the tc ematch function em_ipset will be disabled.
