Subject: [PATCH] Removed timezone usage in UnixRealTimeClock::CurrentTimeVal
 when calling gettimeofday.

Timezone (tz) was unused in this case. When porting webRTC to certain platforms it caused runtime asserts when unsupported.
Additionally, the timezone parameter is obsolete and should now be NULL according to
https://man7.org/linux/man-pages/man2/gettimeofday.2.html.
