[PATCH 3/9] boilerplate/ancillaries: prevent false positive with -Wstringop-truncation

[Philippe Gerum]

namecpy() is meant to copying NUL terminated strings even if this
incurs potential truncation of the source argument if need be, prevent
GCC 8.x from detecting a false positive when -Wstringop-truncation is
in effect.
