remove GPL license

Remove the GPL LICENSE file from the repository. I believe this is allowable 
because:

* The binary Linux kernels which are subject to GPL have been removed.
* The only remaining copyright holders are myself or my employer Isovalent.

Here is a list of all authors for each remaining file in the repo:

    ./llvm-snapshot.gpg
   author-mail <[email protected]>
   ./config
   author-mail <[email protected]>
   author-mail <[email protected]>
   author-mail <[email protected]>
   ./build-vmlinux.sh
   author-mail <[email protected]>
   ./configure-vmlinux.sh
   author-mail <[email protected]>
   ./copy-selftests.sh
   author-mail <[email protected]>
   ./env.sh
   author-mail <[email protected]>
   ./build-selftests.sh
   author-mail <[email protected]>
   ./download.sh
   author-mail <[email protected]>
   ./llvm.pref
   author-mail <[email protected]>
   ./llvm.list
   author-mail <[email protected]>
   ./VERSION
   author-mail <[email protected]>
   ./.github/workflows/images.yml
   author-mail <[email protected]>
   ./Dockerfile.builder
   author-mail <[email protected]>
   ./Makefile
   author-mail <[email protected]>
   author-mail <[email protected]>
   ./README.md
   author-mail <[email protected]>
   author-mail <[email protected]>
   author-mail <[email protected]>
   ./buildx.sh
   author-mail <[email protected]>
   ./versions.json
   author-mail <[email protected]>
   ./Dockerfile
   author-mail <[email protected]>
   ./LICENSE
   author-mail <[email protected]>
   author-mail <not.committed.yet>

This was generated using

    for i in $(find . -name .git -prune -o -type f -print); do \
       echo $i; git blame --porcelain $i | grep -a "author-mail" | sort -u;
\
   done

The file config still contains lines which I contributed while working for
my old employer Cloudflare, but I believe that these changes do not meet the
threshold of originality.
