glocalfileinfo: Preserve microseconds for access/modify times

Browse Source 
When setting the file time using utimensat, don't ignore
microseconds for access/modify times. By doing that, they're preserved
when using g_file_info_set_modification_date_time and then setting the file's
attributes from it.

Fixes #3116
