archive: drop the leading '.' path component from the prefix (issue4634)

Unix utilities like tar will happily prefix the files it packs with './', but
annoyingly, Windows Explorer will not show these packed files when it opens the
archive.  Since there doesn't seem to be a point in including './' in the path
names, just drop it.  The default 'hg archive' prefix is the basename of the
archive, so specifying '.' allows for that default to be disabled completely.
