[src/trunk]: src/tests/lib/libc/stdio Make opts.cmd const char * rather than ...

description:
Make opts.cmd const char * rather than char * -- nothing ever modifies
the string it points to, it is never passed to a function not taking a
const char * arg, and this allows "" (or other literal strings if ever
needed) to be assigned to it - which should fix the build.
