Please make it more obvious that the .orig file check is fatal
Originally created by @lamby on #15727 (Redmine)
When patches are fuzzy and leave .orig files around, we bail out of the build. However, without some kind of “error” / “fatal” or even “E:” prefix it is not obvious whether this a warning or a fatal error.
Trivial patch attached that uses E: to match the live-build style.
