cmdutil.service: do not _exit(0) in the parent process

The fact that a parent process spawns a daemon does not necessarily means that
it is the only think it has to do. This was forcing since 7c01599dd340 inotify
processes launched implicitely to exit prematurely:
when no inotify server was running, "hg st" for example would only launch a
inotify server, _exit(0) and thus would not return file statuses.

This changeset adds a test for implicitely launched inotify processes.
Change to output of test-inotify-1208 is correct: it reflects the normal
error message of "hg st" when not dying during "hg inserve" daemon creation.
