kernel: delete Linux 5.4 config and patches

As the upcoming release will be based on Linux 5.10 only, remove all
kernel configuration as well as patches for Linux 5.4.
There were no targets still actively using Linux 5.4.

-Subject: [PATCH] wireguard: selftests: tie socket waiting to target pid
-
-commit 88f404a9b1d75388225b1c67b6dd327cb2182777 upstream.
-
-Without this, we wind up proceeding too early sometimes when the
-previous process has just used the same listening port. So, we tie the
-listening socket query to the specific pid we're interested in.
