[PATCH] uml: Fix handling of failed execs of helpers

There were some bugs in handling failures to exec helper programs.  errno was
passed back from the child with the wrong sign.  It was also ignored.  In the
case where it mattered, the errno from the (successful) read in the parent was
used instead.
