utmp: Avoid -Wstringop-truncation warning
The -Wstringop-truncation option new in GCC 8 detects common misuses of the strncat and strncpy function that may result in truncating the copied string before the terminating NUL. To avoid false positive warnings for correct code that intentionally creates sequences of characters that aren't guaranteed to be NUL-terminated, arrays that are intended to store such sequences should be decorated with a new nonstring attribute. This change add this attribute to Glibc and uses it to suppress such false positives. ChangeLog: * misc/sys/cdefs.h (__attribute_nonstring__): New macro. * sysdeps/gnu/bits/utmp.h (struct utmp): Use it. * sysdeps/unix/sysv/linux/s390/bits/utmp.h (struct utmp): Same. (cherry picked from commit 7532837d7b03b3ca5b9a63d77a5bd81dd23f3d9c)
