[PATCH 3/4] clock: Remove time_beginning

[Jules Maselbas]

The output of the `demsg -t` command will have broken timestamps for
every log entries written (in the log) before switching clock.

The function get_time_ns() is monotonic, thus setting time_beginning
with get_time_ns() when switching clocksource will always result in
time_beginning being greater than every timestamp set before.
