Auto merge of #396 - Marwes:gluon, r=pietroalbini

Re-add gluon* to the crater list

I think gluon was blacklisted due the problem in #157
but that has since been fixed in the crate itself so gluon now compiles
(verified by running crater locally).

Found because I started getting the warning from rust-lang/rust#57501 in gluon_vm.
