Fix -Werror=unterminated-string-initialization errors

GCC 15 has introduced errors for "unterminated-string-initialization"
Which treat any character array initialised with a string with a larger
size such that the null-character is not getting included in the
character array, GCC 15 gives a warning (and warnings are treated as
errors in skiboot compile).

This causes following errors on compiling skiboot with GCC 15:

    core/init.c:79:27: error: initializer-string for array of ‘unsigned char’ truncates NUL terminator but destination lacks ‘nonstring’ attribute (9 chars into 8 available) [-Werror=unterminated-string-initialization]
       79 |         .eye_catcher    = "OPALdbug",
          |                           ^~~~~~~~~~
    cc1: all warnings being treated as errors
    ...

    In file included from hdata/hdata.h:8,
                     from hdata/spira.c:17:
    hdata/spira.c:35:32: error: initializer-string for array of ‘char’ truncates NUL terminator but destination lacks ‘nonstring’ attribute (7 chars into 6 available) [-Werror=unterminated-string-initialization]

          |                                ^~~~~~~~

          |                                                                    ^~~
    hdata/spira.c:35:16: note: in expansion of macro ‘HDIF_SIMPLE_HDR’

    ...
     (similar errors few more times with hdata)
    ...
    cc1: all warnings being treated as errors```

Fix the errors by marking character arrays which are not supposed to be
"null-terminated strings" with "nonstring" attribute, such as
eye-catchers in skiboot debug descriptor and hdif header
