Description

Build error with gcc 10:

../fruraw.c: In function 'frt_get_segment_name':
../fruraw.c:552:41: error: writing 1 byte into a region of size 0 [-Werror=stringop-overflow=]
  552 |     segs[each_seg].name[FRU_SEGNAMELEN] = '\0';
      |     ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~^~~~~~
In file included from ../fru_access_impl.h:50,
                 from ../fruraw.c:32:
../fru_access.h:62:7: note: at offset 2 to object 'name' with size 2 declared here
   62 |  char name[SEG_NAME_LEN]; /*  from container section header  */
      |       ^~~~

This issue is about writing past array end.

Testing done: build/install/boot
