util/cbfstool/eventlog: Use LocalTime or UTC timestamps

Add a new flag "--utc" to allow the user to choose if
elogtool should print timestamps in Local Time or in UTC.
It is useful for generating automated crash reports
including all system logs when users are located in
various regions (timezones).

Add information about timezone to timestamps printed
on the console.
