For some reason, cargo incremental doesn't work as well as it should,
and doesn't perform as well as sccache does. So when building with
sccache, disable cargo incremental. This brought a no-change clobber
build with 100% cache from 3:50 to 2:05 on a beefy AWS instance I was
testing this with.

I got the second part backed out because js_options that have varying behavior but not through its default make the default the value used in js... so here that means automation started enabling cargo incremental in js/. Not great. I'll file a followup to handle the "Allow to forcefully enable cargo incremental" part.
