timedatectl: assert timezone is not null in setenv() call.
setenv is declared as: extern int setenv (const char *__name, const char *__value, int __replace) __THROW __nonnull ((2)); And i->timezone can be NULL, if for example /etc/localtime is missing. Previously that worked, but now result in a libc dumping core, as seen with gcc 2.22, due to: https://sourceware.org/ml/glibc-cvs/2015-q2/msg00075.html
