kernel-5.4: bump to 5.4.102 and refresh patches

5.4.102 backported a lot of stuff that our WireGuard backport already
did, in addition to other patches we had, so those patches were
removed from that part of the series. In the process other patches were
refreshed or reworked to account for upstream changes.

This commit involved `update_kernel.sh -v -u 5.4`.

+Subject: [PATCH] wireguard: selftests: reduce complexity and fix make races
+
+commit 04ddf1208f03e1dbc39a4619c40eba640051b950 upstream.
+
+This gives us fewer dependencies and shortens build time, fixes up some
+hash checking race conditions, and also fixes missing directory creation
+that caused issues on massively parallel builds.
