W32: correctly use st_ctime

Browse Source 
On Windows st_ctime field is the file creation time.
POSIX mandates that field to be the file state change time.
Naturally, glib code interpreted st_ctime as POSIX suggested,
and the result was bad.
Fix this by introducing special W32-only logic for setting
attributes from st_ctime field.

Fixes issue #1452.
