Stefan Liebler 1e0c8356f5 nis: Fix stringop-truncation warning with -O3 in nis_local_host. 
When building with -O3 on s390x/x86_64, I get this stringop-truncation warning
which leads to a build fail:

In function ‘nis_local_host’,
    inlined from ‘nis_local_host’ at nis_local_names.c:147:1:
nis_local_names.c:171:11: error: ‘strncpy’ output may be truncated copying between 0 and 1023 bytes from a string of length 1024 [-Werror=stringop-truncation]
171 |           strncpy (cp, nis_local_directory (), NIS_MAXNAMELEN - len -1);
       |           ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

We can just ignore this warning as the hostname + '.' + directory-name + '\0' always fits
in __nishostname with length of (NIS_MAXNAMELEN + 1) as there is the runtime check above.
Furthermore as we already know the length of the directory-name, we can also just use
memcpy to copy the directory-name inclusive the NUL-termination.

Note: This werror was introduced with commit
32c7acd464
"Replace rawmemchr (s, '\0') with strchr"
