[BusyBox] tar won't overwrite existing files

[Steven Scholz]

Hi there,

I noticed that busybox tar won't overwrite existing files when extracting.

Could we implement some of these features please:

   -k, --keep-old-files       don't replace existing files when extracting
       --overwrite            overwrite existing files when extracting
   -U, --unlink-first         remove each file prior to extracting over it
       --recursive-unlink     empty hierarchies prior to extracting directory

I'll need the "--overwrite" option.
