supervise-daemon: Fix segfault when executable does not exist

Browse Source 
When executable is provided just by name (and therefore searched in a
path), exec_file is reset to NULL every time. exists() handles it being
NULL just fine, but dereferencing it in eerror does not work.

Fixes #326
Fixes #327
