glib: Format GDateTime ISO8601 years as %C%y

Browse Source 
The current use of %Y does not take into account that %Y will
not pad the year with 0's, meanwhile ISO8601 does expect a full
YYYY format for all dates. This breaks the formatting with dates
prior to the year 1000.

Split this into %C%y so 2-digit, 0-padded century and year are
printed separately, this gives the expected YYYY format.
