Suppress new gcc-15 -Wunterminated-string-initialization

GCC 15 now warns when character arrays are being initialized by strings
and terminating NUL character doesn't fit. GCC 15.1 also allows marking
such arrays with nonstring attribute to suppress the warning. W/o such
attribute, the warning becomes error due to the global -Werror. Add the
attribute accordingly.

Fixes these errors:
