[LU-20094] Buffer overflow detected when reading YAML file using old API

Description

lnetctl import could lead to:

*** buffer overflow detected ***: terminated
Aborted (core dumped) 

The buffer used when reading YAML file with fgets in old API is 1 byte too small: we need to store '\0'.

Also wrong length is given to fgets because strlen is called on modified buffer instead of the old one.
