[PATCH] 30_os-prober.in: only warn if os-prober is available

[Sertonix]

From: Christoph Anton Mitterer <mail@christoph.anton.mitterer.name>

It doesn’t make sense to warn that os-prober is not going to be executed when
that isn’t available anyway.

 The initial patch was attached in this bug report: 
https://savannah.gnu.org/bugs/index.php?61718
 I simplified it slightly.
