doc: indicate Type=oneshot also detects invocation failures

Type `simple` explicitly mentions that invocation failures like a missing binary
or `User=` name won’t get detected – whereas type `exec` mentions that it does.

Type `oneshot` refers to being similar to `simple`, which could lead one to
assume it doesn’t detect such invocation failures either – it seems however it
does.

Indicate this my changing its wording to be similar to `exec`.
