Roland Shoemaker 791f758075 archive/zip: tolerate compressed directories with zero uncompressed size
In CL 449955 we made reading of directories with associated file data
an error, since it is a "must not" in the zip specification. It turns
out that a number of implementations make the mistake of not setting
the correct compression method on directories (in particular the Java
jar tool does this when storing the META-INF directory). If the
compression method used is not 0 (stored) then the compressed size of
the directory can be > 0, despite the uncompressed size still being 0.

Since this mistake is not uncommon, we are forced to tolerate it. We
still fail if the recorded uncompressed size is > 0, which should be
a significantly harder mistake to make.
