g_date_time_format: drop %N format

%N is not specified in any standards document, but we use it to display
the number of microseconds.

The fact that our our current implementation of it is nearly useless
(since it does not zero-pad) coupled with the high chance that a future
version of the C standard may specify it with another meaning means that
we should drop it.
