Subject: [PATCH 80/89] Include count for \0 character when using strncpy to
 implement strdup.
Git-commit: 7d90f7603af6b59e7144cef6617a1e9dd42161bd
Patch-mainline: mdadm-4.1+
References: jsc#SLE-13700

We have to include the \0 character in the length when copying a
string with strncpy() for which length was found with strlen().
Otherwise the destination will not get null terminated - except that
we explicitly zeroed it out earlier.

This quiets down the compiler's warnings.
