In 321fd823 ("run-command: mark path lookup errors with ENOENT",
2018-10-24), we rewrote the logic to execute a command by looking
in the directories on $PATH; as a side effect, a request to run a
command that is not found on $PATH is noticed even before a child
process is forked to execute it.
We however stopped to report an exec failure in such a case by
mistake. Add a logic to report the error unless silent-exec-failure
is requested, to match the original code.

* Strictly speaking, the failure that is diagnosed by the spawned
child is reported with die() and prefixed with "failure:"; I am
adding error_errno(), so this will be reported with "error:"
prefix, which is a slight change in behaviour, but I am guessing
that this should be OK.
