timedate: remove daylight saving time handling and tzfile parser
We planned to support (the conceptually broken) daylight saving time/local time features in the kernel, SCSI, networking, FAT filesystem, but it turned out to be a race we cannot win and do not want to get involved. Systemd should not fiddle with daylight saving time or parse timezone information itself. Leave everything to glibc or tools like date(1) and do not make any promises or raise expectations that systemd should handle anything like this.
