gio: add a file copy flag for default modification time

Browse Source 
Add a default modification timestamp flag to g_file_copy so that it
doesn't copy the modification time from the source file as it does by
default. Similarly to G_FILE_COPY_TARGET_DEFAULT_PERMS, this flag
overrides the G_FILE_COPY_ALL_METADATA flag.
