[PATCH 4/4] archive: queue directories for all types of pathspecs

["René Scharfe" <l.s.r@web.de>]

When read_tree_recursive() encounters a directory excluded by a pathspec
then it enters it anyway because it might contain included entries.  It
calls the callback function before it is able to decide if the directory
is actually needed.

For that reason git archive adds directories to a queue and writes
entries for them only when it encounters the first child item -- but
only if pathspecs with wildcards are used.  Do the same for literal
pathspecs as well, as the reasoning above applies to them, too.  This
prevents git archive from writing entries for excluded directories.
