archive: pass thru mtime for directory archives, like the other archive types do

Without this files in the output archive directory have their mtimes set to
whatever time they were written their.  This is in this inconsistent with
the other archivers, eg. zip, which use exactly the same time for all files.

Works on my machine (Windows), but I don't have a *nix box avaialble to run
anything more thourugh, unfortunately.
