The autopkgtest for rust-onig fails with memory errors on i386 and armhf.

Doing some searching I notice that the onig, syntect and bat crates have all had new major versions released.
So I decided to test the latest version of onig on i386, unfortunately that failed too.

I then tried doing a test outside of the "debcargo" environment, I first tried using
an upstream git checkout but that failed to find it's embedded copy of libonig
so I decided to use cargo clone instead.

cargo install cargo clone
cargo clone onig
cd onig
cargo test

I have reported this upstream at https://github.com/rust-onig/rust-onig/issues/155
