The function kunit_status_to_ok_not_ok() returns string literals, thus
declare the return value as such.

Reported by clang:

    ./include/kunit/test.h:143:10: warning: returning 'const char[3]' from a function with result type 'char *' discards qualifiers [-Wincompatible-pointer-types-discards-qualifiers]
      143 |                 return "ok";
          |                        ^~~~
    ./include/kunit/test.h:145:10: warning: returning 'const char[7]' from a function with result type 'char *' discards qualifiers [-Wincompatible-pointer-types-discards-qualifiers]
      145 |                 return "not ok";
          |                        ^~~~~~~~
    ./include/kunit/test.h:147:9: warning: returning 'const char[8]' from a function with result type 'char *' discards qualifiers [-Wincompatible-pointer-types-discards-qualifiers]
      147 |         return "invalid";
          |                ^~~~~~~~~
