liblog: logcat: Add year and zone to date on each line

- '-v year' modifier adds the four digit year prefix
- '-v <timezone>' modifier sets and prints the timezone suffix
- Only promise in logcat to support UTC as a timezone since
  all others are based on the configured environment
- '-v zone' modifier toggles the timezone suffix on or off
- '-T YYYY-MM-DD HH:MM:SS.mmm...' format is added
