Subject: [PATCH] ci: Disable LLVM/debug assertions for distcheck

The purpose of distcheck is to test `./x.py test` from a tarball, not to
test that all assertions pass all the time. These assertions are largely
just redundant with other builders, so skip the assertions for now and
save a good chunk of time on CI.
