udev-cache: strip timestamps on extract
Under normal udev operation, device nodes are obviously timestamped based on the system time at current boot. However, when using udev-cache, they are timestamped from a previous boot. The existence of machines lacking RTCs makes this more than a cosmetic issue: if the current time is set further on in the boot, so that the system time is still 1970 by the time the cache is extracted, tar will print a timestamp warning for every extracted file (potentially hundreds of them). To fix, use -m on extract. If using busybox `tar`, this commit requires CONFIG_FEATURE_TAR_NOPRESERVE_TIME=y.
