As noted by commit 738261290f ("CI: temporarily disable vmtest"),
vmtest was generating too much traffic to the Dropbox shared folder that
hosted vmtest kernels. Instead, we can store kernel packages as GitHub
release assets. Update the code for downloading and uploading vmtest
assets, and also add a scheduled GitHub action to build new kernels
every Monday so I don't have to remember to do it manually.
This also drops vmtest support for 5.6-5.9, which now fail to build with
newer binutils due to the issue fixed in Linux kernel commit
1d489151e9f9 ("objtool: Don't fail on missing symbol table").
