[glib: 1/3] W32: correctly use st_ctime

    W32: correctly use st_ctime
    
    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.
