linux-user: respect timezone for settimeofday

Browse source 
The settimeofday syscall accepts a tz argument indicating the desired
timezone to the kernel. QEMU previously ignored any argument provided
by the target program & always passed NULL to the kernel. Instead,
translate the argument & pass along the data userland provided.

Although this argument is described by the settimeofday man page as
obsolete, it is used by systemd as of version 213.
