EDAC/ghes: Replace deprecated strcpy() in ghes_edac_report_mem_error()

EDAC/ghes: Replace deprecated strcpy() in ghes_edac_report_mem_error()

strcpy() has been deprecated¹ because it performs no bounds checking on the
destination buffer, which can lead to buffer overflows. Use the safer
strscpy() instead.
