libreplace: always provide utime() and utimes()
I'd like to also provide futimes(), but it seems that some systems doesn't support a it at kernel level. If someone knows how to write a portable replacement for futimes() please tell me... metze (This used to be commit a9604fe4a323dccb537cf02ea7594437b4995803)
