[PATCH 1/7] harness: Use destination strncpy() expression for sizeof() argument

Even though this is the same size, as the sizeof() is derived from the
source expression, recent gcc versions will emit a warning, which is
turned into an error by -Werror:

  error: argument to ‘sizeof’ in ‘strncpy’ call is the same expression
    as the source; did you mean to use the size of the destination?
    [-Werror=sizeof-pointer-memaccess]
