sh: avoid warnings about too-long initializer strings

Mark `optletter` and `t_op::op_text` as `__non_string`, to avoid
warnings from clang 21 similar to:

bin/sh/options.h:77:36: error: initializer-string for character array is too long, array size is 19 but initializer has size 20 (including the null terminating character); did you mean to use the 'nonstring' attribute? [-Werror,-Wunterminated-string-initialization]
77 | const char optletter[NSHORTOPTS] = "efIimnsxvVECabupTPh";
| ^~~~~~~~~~~~~~~~~~~~~
bin/test/test.c:153:3: error: initializer-string for character array is too long, array size is 2 but initializer has size 3 (including the null terminating character); did you mean to use the 'nonstring' attribute? [-Werror,-Wunterminated-string-initialization]
153 | {"==", STREQ},
| ^~~~
