log: Correct formatting of timestamps

logtime_fmt_and_arg() is a rather odd macro, producing both a format
string and an argument, which can only be used in quite specific printf()
like formulations.  It also has a significant bug: it tries to display 4
digits after the decimal point (so down to tenths of milliseconds) using
%04i.  But the field width in printf() is always a *minimum* not maximum
field width, so this will not truncate the given value, but will redisplay
the entire tenth-of-milliseconds difference again after the decimal point.

Replace the macro with an snprintf() like function which will format the
timestamp, and use an explicit % to correct the display.
