censor: fix things around inlining
The temporary revlog cannot go through the inline → split process as this would
break at transaction commit. (that might be fixable, but lets keep things
simple for now). We introduce a cleaner way to enforce this as the previous one
was broken in 6.6
On the way we remove multiple weird, fragile and broken overwrite of revlog
attributes and we focus on passing the configuration across.
We also had to update the test to actually create a non-inline revlog.
