Subject: [PATCH] test-process-util: also add EROFS to the list of "good"
 errors

It is only added in the one place where we actually try to set the
setting to a new value. Before we were testing if we can set to it the
existing value, which was a noop. We could still get a permission error,
but this is the first place where we would propagate EROFS.

(cherry picked from commit 6434a83d01d96e9f9a17ed9ce1f04a7d64859950)
